Specializing in hand-cut colored gemstones, GEMFIX INC operates a lapidary arts studio and gemstone showroom from Suite 608 of the San Diego Jewelers Exchange at 861 Sixth Avenue in downtown San Diego. Each stone is faceted by hand using precision cutting techniques that maximize brilliance and fire, an artisan-craft discipline that parallels the original fine-art works shown at Exclusive Collections Gallery in the Gaslamp Quarter. Montana sapphires are the flagship offering, with inventory spanning teal, blue-green, and color-change varieties cut in proprietary faceting patterns not found in commercial-grade production. Every gemstone ships with a Gemological Certificate of Authenticity, and the company encourages independent third-party lab verification — a transparency standard shared by celebration-worthy venues like Extraordinary Desserts. Highest-complexity cuts involve custom concave faceting and fantasy-cut designs on sapphire, garnet, tourmaline, and spinel rough, each shaped to client specifications on precision lapidary equipment.
