The Mark’s Diamonds Distinction

Mark does not simply choose a diamond based on its cut, color, clarity, and carat. He must see the diamond in person.
The four qualities Mark is looking for in a diamond are Love, Beauty, Reverence, and Brilliance.

Our dedication for creating lifelong memories, delivering a customized intimate experience and inspiring service will never waiver.
That is our promise to you.

Round

Round cut diamonds are the most
popular diamond shape partly because the facets
maximize the brilliance, or sparkle, of the diamond.

Radiant

A Radiant cut diamond incorporates the
maximum brilliance of a round diamond but
in the form of a rectangular-shaped diamond.

Princess

A Princess cut diamond is typically a square-shaped
diamond and has become a very popular
style in recent years, second to a round brilliant diamond.

Pear

The pear shaped diamond is faceted to
deliver the most sparkle and brilliance,
similar to a round brilliant diamond.

Oval

An oval diamond can be thought
of as an elongated round brilliant
as it has similar visual qualities.

Emerald

The lengthened form, linear facets, and
large table make Emerald cut diamonds
remarkable. Also, they are more
uncommon--only making up about 3%
of all diamonds in the world.

Cushion

A Cushion cut diamond is similar to a
Princess cut, but it has rounded corners.
In fact, a Cushion cut diamond actually
resembles a pillow.

Asscher

An Asscher cut diamond is considered
a square Emerald cut diamond.
Not much can hide in this cut--you
can see right through the diamond.

Heart

A Heart-shaped diamond has a brilliant cut
to maximize the shine and light play,
plus a little romance.

Marquise

The sleek, "boat shape" design of a
Marquise cut diamond helps to
slenderize the appearance of a finger.

I can't say enough great things about Mark's Diamonds. I bought my wife's engagement ring from Mark and it's now my go-to for gifts. Mark went out of his way to track down a custom diamond and emerald necklace I was looking for and it was PERFECT! The whole team is amazing there and there's no comparison when it comes to the engagement rings. Love Mark's Diamonds.

I was turned down at another place for not having an appointment, I called Marks and they got me in right away. I was able to find a great ring at a really good price thanks to them. Everyone I spoke with there was very friendly and had excellent customer service.

Mark and Ashley were super helpful and friendly. Mark really knows what he is talking about and has an amazing talent for finding exactly what will work for you. I had a small budget and they still treated me like a big client! Excellent timing, and communication, 10/10 would recommend.

My fiancé and I had my engagement ring sized here and we found Bobby and Tim to be very warm and accommodating. The ring sizing was done beautifully and we enjoyed such refreshing and personal customer service. Will recommend to all our friends!

Shopping for an engagement ring is very stressful experience for most men. The lack of knowledge mixed with the large price tag make things difficult and nerve racking. With all that said Mark and his staff made it is stress free as possible. I had full confidence that I was getting the best deal and they had my best interest in mind. It's very clear customer service and satisfaction is a top priority. Mark did an amazing job of helping me understand what I was looking at and the meaning behind it all. I highly recommend using this jeweler.

Working with Mark and his staff was a truly great experience. He helped us to navigate the often confusing and overwhelming process by listening to our goals and preferences and narrowing it down to a few great choices. In the end we have a ring that is more gorgeous than we ever imagined at a great value. I highly recommend Mark’s Diamonds and will gladly tell everyone about my experience. My beautiful ring does most of the advertising though!

I went down to Mark's Diamonds with my watch I inherited from my grandfather. Tim and Mark were both very welcoming, as well as the rest of the staff. Tim resized the wristband for me, polished it up and got a fresh battery installed! Now my heirloom is keeping time like the Big Ben clocktower in London! =D I highly recommend Mark's Diamonds to anyone in need of jewelry or assistance, 5 stars!!

Stone Fox Gems

Great prices and most importantly, great service. Ring was ready on time and when we needed it resized I dropped it off at night and got it back the next day! Highly recommend Mark's diamonds.

Never having purchased a diamond before, I wasn’t quite sure how the process would go. I visited 3 jewelers in cherry creek and chose to go with Marks Diamonds because Mark & his family were all professional, informative, not pushy and best of all the quality of diamond was fantastic and the best deal pricewise of any place I shopped. Would recommend, would shop at Marks Diamonds again.

Mark and his team are extremely professional and high class. They cater to you as an individual and your wants/needs. They have a magnificent collection of jewelry that has a very wide range to fit anyone's taste. Their personal touch to your experience was truly felt and I would highly recommend checking them out for your next piece!

Emma Gordon

Highly recommend! Mark and his team were all so friendly and passionate about helping me pick an engagement ring. I met with Mark and showed him what I wanted and he stayed within my budget and gave me a high quality ring with a quick turnaround. I am so impressed by the personalized service I received and in the future if i need anything i will return to him. Very high quality and great prices and a great overall experience.

Jessica Berry

21:10 11 Sep 18

They did an absolutely amazing job!! I showed him a picture of the ring I wanted over texted and he made it perfect! I completed my entire experience as I was in another state but heard amazing things about this company so I had to use them and I was not disappointed. I highly recommend them for any ring.

Mark and his team create the best possible experience for choosing the perfect engagement ring and wedding band (or jewelry in general.) They have such an intimate setting to allow you to fall in love with every piece of jewelry. Mark is personable and walks you through the process himself. He ensures all your needs are met- style, comfort, privacy, and hydration, etc. His entire team (shout out Bobby) is very knowledgeable of their line of business. There is something about having someone who genuinely cares about their product and wants the customer to feel that genuine admiration. Not only is the quality of the jewelry top notch, he will work with you and your budget because your happiness take priority. If you have an idea of what you want, he will custom design and make it to your liking. I could go on about how wonderful it is to have a jewelry experience like I did at Mark's, but you get the point. Go see Mark!!!

Theresa Rickert

22:04 13 Aug 18

I would no doubt buy a ring here again. Mark told me that he would help me find the ring I was looking for within my budget and he did exactly that! I can guarantee that there is no other store who would sell me the quality of diamond and ring that he did for the price. Mark genuinely wanted to help me get the perfect ring for my fiancé. I will be going back here for any jewelry needs! I highly recommend Mark’s Diamonds to anyone looking for an engagement ring!

Nathan Gorman

01:14 08 Aug 18

Our experience with Mark’s Diamonds was better than we could have ever expected! Bobby really took the time to explain each diamond to my fiancé and I and make sure we were comfortable with our final choice. He went above and beyond when my ring came in and even drove back to the store to make sure I was able to pick it up that night. I was so happy with the my final rig it was everything I wanted! I would highly recommend Mark’s Diamonds to any couple looking for an engagement ring, and we definitely plan to get our wedding bands there as well!

Marina Snellings

Incredible to have found Mark and his team. They made this so easy for me to find the perfect ring. They personalized my experience and made it so fun and stress free. The whole team was so Friendly, and l would highly recommend choosing them over anyone else. THE BEST OF THE BEST..........

Mark was absolutely incredible to work with. In a short meeting he was able to narrow down and build the perfect ring that far exceeded my expectations based on what my price range allowed elsewhere. He is straightforward, honest, and an overall great guy to work with. I would easily recommend him above any other jeweler! I've sent multiple friends to Mark and they've all had an equally wonderful experience.

Samuel Lillie

18:16 30 May 18

My fiance and I wanted a ring that wasn't being made by the designer anymore and Mark's Diamonds was able to recreate our perfect ring flawlessly! They were so nice and helpful in making sure we were happy with our engagement ring! My fiance wishes he had started at Mark's from the very beginning. We showed Bobby a picture of what we wanted and took care of us all the way until the end!

Shelby Morgan

00:33 07 May 18

I had a custom sapphire infinity band commissioned for my 10th wedding anniversary and it's more beautiful than I could have imagined. I've had for 2 years and I now live in Charlotte, NC and I send back to Mark's Diamonds for maintenance and cleaning and Bobby is truly the best. He takes the BEST care of me and my jewelry. Mark's Diamond's is top notch, truly the best. My family wouldn't consider another jeweler. The team understands how special the jewelry is and how the occasion will forever by memorialized by their items. Incredible experience, truly bespoke quality jewelry and excellent communication. Thank you!

This was and continues to be a very pleasant experience. Mark, Bobby, and the rest of the staff are so kind and helpful. I went in expecting to just check out a few engagement rings and to look around at other locations; however, I walked in and was sold right away on what I wanted. Mark made it very simple for me, and he takes care of all of it for you!I highly recommend supporting this business and it's workers!

Paul Ji

19:44 01 May 18

Working with Mark, Bobby, and the rest of the crew at Mark’s Diamonds was nothing short of a fantastic experience. Their knowledge, pricing, and customer service is some of the best I have ever experienced.I have never written a google review until now and no one deserves it more than Mark’s Diamonds. If I could rate higher I would. I would recommend any one to work with them. My fiancé and myself couldn’t be happier with the ring! A+!

Colby Garlick

03:20 26 Apr 18

If I could rank this 6 stars I absolutely would. Cannot recommend this place enough! Exceptional customer service and a genuine and authentic desire to make sure you leave with exactly what you want! I bought an engagement ring there and as a first time diamond/ring buyer it can be overwhelming but the staff at Mark’s Diamonds make it a fun experience. Amazing place!!

Taylor Murphy

22:39 29 Mar 18

We were referred to Marks by a friend. Wow! What a great experience! We were immediately comfortable with everyone on the staff we came in contact with, and at the same time felt lucky to be able to have Mark get to help us chose our stone and ring design. When we found out it would take a perfectly reasonable 3-4 weeks to get the finished ring, which was a custom request, we mentioned in passing how we should’ve come earlier as it would’ve been nice to get the ring before going on vacation to see my Fiancé’s parents. Mark called me the next day and informed me he would do his best to make it happen. I surprised her with her finished ring, exactly like she wanted, in Florida less than two weeks later. I’m not sure if these results can be typical for everyone (disclaimer) , but our experience was wonderful . Highly recommend Mark, Bobby, and the entire Marks Diamonds staff and experience!

18:32 28 Mar 18

We are so pleased with our experience at Mark's Diamonds! Not only did the entire crew chip in to make my perfect ring, they worked extra hard to have it ready for my fiancé to give it to me while visiting my parents. I got a second proposal in gorgeous south east Florida captured on film with my parents there to witness it all! Mark was amazing to work with and made us feel at ease about everything. And I got the ring of my dreams!

Trish Gallagher

18:27 28 Mar 18

I have never experienced this level of customized and personalized customer care. Absolutely extraordinary! I came in and the entire process was so low stress and flawless. I was greeted and treated in a very professional but personalized manner. Mark quickly got down to business and helped me to design a completely custom engagement ring from my challenging criteria. I cannot recommend this team enough!

Mark Steinke

18:01 08 Mar 18

Bobby was the best! The whole entire process of getting the engagement ring was painless! I came with a picture and he guided me the entire way. He educated me on picking the right diamond and the right band. The ring was exactly what my fiance wanted! Such great quality and my fiance gets compliments daily about the ring! I will recommend Mark's to everyone and we will be going back to get our wedding band or any jewelry in the future!

Chris Velgersdyk

21:01 19 Feb 18

Mark's Diamonds was a referral from a referral, which should tell you what you need to know. While the pricing is more than fair, the customer experience is why you really shop here. They are incredibly knowledgeable and have a fantastic selection of unique and one of a kind pieces. There is no pressure from the staff, instead their primary concern is to ensure that when you walk out you are elated with your purchase.They also have the ability to take any design or idea that you would like to create and have it custom made.We will never buy jewelery anywhere else!!!

Geoff Keller

03:37 11 Feb 18

I purchased my engagement ring at Marks diamonds in December 2017. Mark and Bobby deserve a 5 star rating. Each meeting was 1 on 1, and Mark was able to show me many options in a couple of different meetings until we found the perfect stone. Both Mark and Bobby were responsive all days of the week, and were accomdating in fitting the band after the proposal. I highly recommend Mark’s diamonds for anyone purchasing an engagement ring.

Peter Skogg

16:28 23 Jan 18

Had an incredible, stress-free experience purchasing an engagement ring from Mark and his staff. From the friendly front door greeting to Mark taking the extra time to go over all the options with me, this was far and away the best service I have ever experienced. The ring turned out incredible and my fiancée still can't stop looking at it! Highly recommend!

Josh Hill

03:56 11 Jan 18

If you are looking for someone who will go above and beyond your expectations and needs then Mark is your guy. Mark really does treat you like family whether it is your first time in there or your 50th. Not only that but you can not beat his quality and connections. With all of the above I would give Mark 10 no 100 stars if I could. Mark really made an extra effort in assisting me with creating a truly special engagement ring for my fiance and honestly it's one of a kind. I could not have done this without Mark's attention to detail, dedication, and determination to expert customer service. Mark is my only choice in anything related to jewellery and I implore you to reach out and see what Mark can do for you, you will not be disappointed. Thank you Mark!

Chris Pfarr

20:15 07 Jan 18

I brought my wedding rings for resizing. The staff were so kind and helpful. My rings were resized perfectly and cleaned professionally. They look like new. What an excellent experience. I highly recommend this store above all others. Very, helpful and professional.

Kelly Diaz

10:14 07 Jan 18

Couldn't recommend highly enough. Great staff that will truly take care of you. Was able to buy my fiance her dream ring and Mark and his team were able to pull off a miracle last minute order request to meet my proposal plans!I did not receive the individualized treatment anywhere else I shopped. Great value and amazing quality.

Ty Hoffman

08:14 31 Dec 17

The experience with Mark’s Diamonds was awesome! The staff is respectful, kind and honest. They made me feel like I belonged there, I couldn’t afford most of the jewelry in there but they made feel like I could ,if that makes sense! All I know is I would recommend this place to anyone, looking to fix your jewelry to buying nice jewelry, definitely let this be the place you decide to go! I am so happy I chose this place I strongly suggest makeing this your jewelry spot!

Joe Diaz

00:50 21 Dec 17

Mark and team are the best jewelers in town! They're extremely friendly and welcome you to the store with hugs - always snatching the jewelry you're wearing for a complimentary cleaning while you're there. The selection is great, and even better when you want something custom. They'll work within your budget and design ideas to get exactly what you want - whether it's with their in-house jeweler or special ordered. They're happy to show you any piece of jewelry in the store, and Mark works tirelessly to help you find the perfect piece. I especially love the ready-to-wear and vintage pieces they carry that make great "thoughts" for special people in your life. Mark will go above and beyond (and has for us many, many times over the years). Every special piece of jewelry, we got from Mark. We're customers for life.

Kali Handford

23:40 20 Dec 17

Mark provided a great purchasing experience. We had an idea of the ring we wanted and Mark was able to recreate it with higher quality materials. We highly recommend Mark’s Diamonds if you’re looking for quality engagement rings for a fair price.

Derek Chandler

19:58 04 Dec 17

This is definitely the place you want to make your jeweler in Denver. I’ve been to a number of jewelers around town in search of lowering my engagement setting. No one else would do this (including the place my ring is from!) and Marks Diamonds said it would be no problem and it was finished two days! Exactly how I wanted it, too. They are by far and away the best. They are extraordinarily personal and accommodating. Tim, their jeweler, can literally do anything you want and is such a wonderful person to work with. Please dont go anywhere else! Save yourself the trouble and headache of dealing with sales-y jewelers and go here to get exactly what you’re looking for. Wish we had started here.

Lauren Johnson

16:30 16 Nov 17

I just wanted to take a moment and thank you for repairing my ring today. I was not expecting for you to say "bring it over" or "we will have it done in 20 minutes." On top of that, it looks just as good as when my husband gave it to me almost 4 years ago! We really appreciate your great customer service! Thanks again!

Sarah Mlynek

15:21 15 Nov 17

When making such an expensive and emotional purchase such as an engagement ring, the experience truly makes all the difference. Mark and his team treat their customers with respect and appreciation. More importantly, they are experts at what they do and will help you find the perfect option. Thank you Mark!

Robert Webb

16:01 10 Nov 17

Highly recommended. Go to Mark's.. You will be extremely satisfied. They go above and beyond and will give you the best you can find for the best price. They are always on top of their communication, and on time. We got engagement ring and bands from here, and they never stop sparkling like the ads you see everywhere. You will not get a better deal anywhere else.

Maximo Saladino

21:00 09 Nov 17

Mark's Diamonds is simply the best. Mark selflessly took time out of his Labor Day to meet with me in order to pick the engagement ring, diamond, and wedding band. Not only that, but he was sympathetic to my budget and was able to help me pick beautiful rings that I'm not only proud of, but they were within my budget too. Furthermore, my fiance loves the ring and has received countless compliments on it. If you are looking for a high quality ring, diamond, experience, etc. look no further than Mark's Diamonds.

Stephen Boyer

03:31 24 Oct 17

Mark’s Diamonds was a great experience! Buying an engagement ring for my fiancé was not easy (at least I thought) until I found Mark. He made it very clear, educating, fun, and special. My fiancé loves her new ring and we couldn’t be happier. Thanks Mark and team

Omar Sadaoui

02:38 10 Oct 17

Mark's Diamonds team make memories last forever.My husband recently died and I had an idea for his wedding ring that I needed professional jewelers to realize. I wanted to combine my husband's and my own yellow gold wedding rings together, add silver on the outside, for a two-tone look, and then add an Art Deco design to the "One ring to rule them all". I met with Bobby and Tim. First, Bobby was very gracious and sympathetic to my new grief riffled life and situation. He listened intently and proceeded to introduced me to Tim, their Master Jeweler, to present my idea to him and come up with a game plan. Tim, also gracious and kind, took my idea and made it better. Instead of silver, which is soft, he chose white gold. He then rolled out our rings and made them one, hand-hammering it into shape. If I understand the next step, he took a white gold ring, subtracted from the underside of that ring and added our yellow gold to make it two-tone. He ended up injuring himself in the process. So my final ring was made with blood, sweat, and tears. He is healing up nicely. Tim then sent it to their professional experienced engraver artist to add the Art Deco design I mentioned. The final result blew my mind and I am ecstatic and so very thankful for this ring, for their kindness, artistry, and craftsmanship - for the forever memory they helped me keep. If you need any jewelry, custom or no, you need to visit these wonderful artists. Thank you from the entirety of my heart!

I have had the pleasure to work with Mark in picking out my wife's engagement ring, wedding ring, and newest ring celebrating our new child. He is extremely easy to work with and always goes the extra mile to make sure his clients are satisfied. I have recommended Mark's Diamonds to several friends and family members, and will continue to return to Mark's Diamonds for all of my future jewelry needs. Thanks Mark and Natalia!

Jon Braun

02:47 14 Sep 17

Mark reset my original diamond from my old engagement ring into a beautiful setting that is a show stopper! I get compliments on it all the time. Recently I stopped in and saw a diamond necklace that is very similar to my new rings that I had to have. I've sent several friends there as well as my son for that special ring and Mark and his staff hit it out of the park for everyone I've referred to him.

Janet Rost

22:08 12 Sep 17

Mark and his team are incredible. I could not be happier with the service, the price, but most importantly the ring. Mark can make anything possible and he did for us. He worked with me to customize the ring to exactly what I wanted and he helped me pick out the perfect diamond with amazing quality and also in my price range. I really can't say enough good things about my experience. I feel very fortunate to have found his store.

Stanley Antolak

21:08 11 Aug 17

We had a wonderful experience with Mark's Diamonds, being out-of-State, we were so surprised with how fast they were! The ring is so incredibly beautiful, and they crafted a special matching band. I couldn't believe how identical he made the band.We're so happy with the ring, and we would definitely recommend going there. Very fast service, super accommodating, and gorgeous quality.

Jarin Wadiwalla

17:12 08 Aug 17

Mark and his team are courteous and helpful. They make one feel special almost like a celebrity with the red carpet treatment. I find that the experience is much different than that of a retail store. After experiencing what Mark's Diamonds has to offer and how one is treated by the staff, I can honestly highly recommend Mark Hadley and his operation to anyone without hesitation. I made the right decision when I ended up choosing to go to Mark's. No regrets. Much better experience than any retail store I visited. Very professional business. Highly recommended.

Thomas Reinke

03:44 20 Jul 17

Long story... End result was Mark and Terry rebuilt my Rolex watch band in house and did a fantastic job for a great price. I have never written a review before because I have not been impressed with a company enough to take the time. I will go back for any of our jewelry needs in the future. Keep up the great work! Bob

Teri Colbert

16:27 10 Jul 17

Mark has been my jeweler for at least five years now. He and his wife and Natalia have a very personal way of taking care of their customers. Mark's designs, resources, fast turnaround and amazing prices make him my absolute go-to favorite in Denver! In addition my husband is comfortable going in to see him knowing that he will always pick something that I love. And if I don't, there is never any question about exchanging or modifying it. Mark and Natalia are two of the most generous people I know. They have always given a fabulous piece of jewelry to the causes I've been involved in.

Debra McKenney

21:10 16 Jun 17

I could not have asked for a better experience with purchasing the engagement ring and wedding bands. Mark and his staff were patient and timely. Most important I found everything to be of high quality and reasonably priced. I have and will continue to recommend Mark Diamonds.

Jordan Becker

16:52 15 Jun 17

What a wonderful experience. Mark added two beautiful bands to my engagement ring and it really took my ring to another level! Not only was his turn around time fantastic, but after getting the bands he messages me pictures and made a new suggestion before finishing the ring and it looks so, so much better than it would have had he done what I originally thought I wanted. It's so gorgeous.After working with him, I found out that last year he actually donated a very, very large amount of fine jewelry to the nonprofit I work for to be auctioned off on behalf of abused and neglected children. Amazing jeweler AND philanthropist? Yes please! Thank you so much, Marks Diamonds!

Alexandra Beard

20:13 18 May 17

Mark's Diamonds is a wonderful store with a good selection of diamonds and a first rate staff that treats people as they would royalty. From the beginning, you are given the red carpet treatment and you are made to feel comfortable while you are being educated about your options to help ensure that you make the best buying decision. Mark and his team guide you through the buying process as a friend to help you. They are not sales people... they are consultants helping friends make the best decision for their circumstances including budget. I have not seen this type of consultative approach by a jeweler in my entire life. They truly become your friends. Mark and team should be commended for how they work diligently to establish friendships with their clients and make clients feel like part of the family. I cannot think of a better place in the world from which to buy an engagement ring and wedding bands. I have traveled all over the world and have not received a better experience. Thank you to Mark and his team for an amazing experience.
