Jewelry Repair and Remodeling

If you’re not ready to let go of sentimental pieces of jewelry, you should consider remodeling. We can upcycle old-fashioned or inherited rings, necklaces, bracelets and earrings for a more modern design.

Your jewelry will look and feel as good as new once we’ve fixed what’s broken. Whether it’s extending the length of a necklace/bracelet, replacing clasps or adding watch links, we assure you that our repair specialists will get the job done quickly and efficiently.


Gold and Rhodium Plating

Rhodium electroplating on jewelry provides a scratch and tarnish-resistant surface that gives a white, almost reflective, appearance. It would be too expensive (and difficult) to make and maintain jewelry made entirely out of rhodium, so we offer plating that lasts the longest on white gold, but will look great on all pieces.


Diamond Setting

The experts at Gold Knox Jewelry are well-versed in diamond setting techniques and styles. We offer unique design elements and cater to your preferences.


Ring Sizing

A common issue with rings is that they may be too big or too small after a while. We offer ring resizing to adjust the circumference to your exact size so it fits comfortably without sacrificing durability. The procedure is done seamlessly with little no visibility of adjustment.


Watch Repair

Our watch repair technicians will replace defective controls, wiring, hardware and apparatus. We can change batteries, straps, perform resizing and polish your prized watches.
