Star Diamond is a full-service jewelry producer and buyer of precious stones, metals, and diamonds based in San Diego, California. The company supplies wholesale diamonds ranging from small melee stones to stones over 50 carats and provides end-to-end jewelry design and manufacturing, including CAD design, wax modeling, precision casting, diamond selection, setting, and finishing. It also purchases precious stones and metals and maintains access to fancy colored diamonds—natural or enhanced—in various sizes and shapes, along with a range of fancy-shaped melee such as princess, baguette, marquise, pear, oval, Asscher, Radiant, and Ideal-cut. Star Diamond operates the Star Diamond & Jewelry Store on eBay, selling vintage, retro, and modern jewelry; the store holds Platinum-level Power-Seller status and is recognized for fast, safe shipping and service. The physical presence is within the Jewelry Exchange building in Downtown San Diego, with in-house cleaning, polishing, and repair work performed by an in-house jeweler. In February 2023, Stardiamondsandiego announced a partnership with Rio Tinto Limited, though Rio Tinto later signalled winding down its involvement.
