THe Mark’s Diamonds Guarantee

Warranty for a Lifetime

At Mark’s Diamonds, we take the utmost pride in the quality of our jewelry which is why we offer a lifetime warranty on all our engagement rings and fine jewelry. Our lifetime warranty covers ring re-sizing, re-polishing, cleaning, rhodium plating and missing accent diamonds*. Most of these services can be done in our showroom by our jewelers while you wait.

For customers outside of Colorado, you can request a shipping label from our Customer Service team to ship your item to our Colorado headquarters for warranty service.

Regarding a service that is not covered under our lifetime warranty, you may request for a piece to be evaluated by one of our master jewelers to restore your piece of jewelry. We will provide a price quote to you directly, and of course, await your approval prior to beginning a jewelry service.

*Additional fees may apply to replacing accent diamonds depending on quality, quantity, type of jewelry metal, etc. Please contact our Customer Service team with further questions.
