We specialize in restoring vintage pieces such as antiques, heirlooms or estate jewelry. Our refurbishing services range from diamond replacements to complete restoration.

Older vintage jewelry tends to have lived a life of previous repairs, often resulting in poor quality. At RockShop, our highly detailed fine repair work can typically undue prior damage and restore your unique vintage piece to its original (or reimagined) beautiful condition.

As not only an independent jewelry design house, but also jewelry appraisal experts with decades of combined experience in the business.

With thorough research, knowledge and precise reporting, we begin the appraisal process by determining the current market value of diamonds, gemstones, antiques, and other types of jewelry — regardless of their age. We bring accuracy, precision, fairness and transparent honesty to everything we do, including our appraisal services.

Our appraisal also includes advice on how to insure your jewels and bespoke pieces against loss, theft or damage. Let us help you discover the value of your jewelry by watching our appraisal process in person at our studio.

As a graduate of the Gemological Institute of America, master jeweler and gemologist Carlos Lopez has the unique capacity to provide diamond and gemstone certifications.

Carlos Lopez’s love for jewelry making began with gemstones. Carlos has been cutting gemstones for over a decade, servicing thousands of clients and creating thousands more custom-cut pieces.

From cutting gemstones from rough (including the ton of turquoise he acquired from a mine in Arizona) to repairing broken gemstones, gemstone drilling, cutting slabs, trimming and cobbing. Contact us to learn more about our stone cutting services.

As part of our comprehensive refurbishing and restoration wheelhouse, we offer restringing for pearls and beaded gemstone jewelry. For durability and preventative safety, it’s best to restring pearl or beaded jewelry every 5 to 7 years. Contact us for a free estimate.

Time marches on, and so should your watch. RockShop provides watch repair and maintenance services, in addition to battery replacement.
