Founded in 2001, Double Happiness Jewelry produces designer pieces from Suite 205 at 1706 Fifth Avenue in downtown San Diego's Bankers Hill. The line's creative use of hand-wrought metal, wire, and hand-set semi-precious stones occupies a designer-art niche alongside galleries like Mee Shim Fine Art in downtown's creative corridor. Signature collections include Stalagmite-inspired earrings with hand-set crystals, heavy gold cuff bracelets, Mosaic-collection pendants in garnet, onyx, and crystal, and Turkish tile-inspired pieces in seductive metalwork. With approximately eleven employees and a wholesale division, the company supplies retailers nationally while maintaining a design-studio showroom that complements the curated interiors at Mobiliti Interiors. Highest-complexity pieces involve multi-material constructions combining hand-formed precious-metal wire, bezel-set cabochon gemstones, and pavé crystal inlays across articulated hinge mechanisms.
