Diamond Trade-up Program

Free Lifetime Diamond Upgrade

King Jewelers offers a free lifetime natural diamond upgrade. Any single stone natural diamond earrings or loose natural diamond purchased from King Jewelers, can be exchanged for credit equivalent to the original purchase price towards a new diamond. To be eligible, the diamond(s) being upgraded must be accompanied with original documentation and must be in saleable *condition.

Upgrades are not available for colored gemstones, settings and jewelry, or lab created diamonds. Upgrade credit does not include tax paid on the original purchase. All applicable duties and taxes will be charged on the full retail price of the new diamond before any credit is applied.

If the upgraded diamond cannot be set in your original engagement ring setting, you can exchange it for a precious metal credit as determined by King Jewelers. We will recycle gold or platinum jewelry and offer a credit based on current metal prices. Please call us at 781-383-1755 for more information on our diamond upgrade policy.

If you didn’t purchase your original diamond stud earrings or diamond engagement ring at King Jewelers, we will offer you a fair trade-in price and you can still trade up.

Please stop by anytime, and we will help you select an extraordinary diamond(s) for your collection.

*no diamonds with chips, fractures or other damage as determined by our gemologist will be acceptable.
