We offer custom design consultation, restoration and jewelry fabrication. Each Single Stone San Marino custom piece is skillfully handcrafted and proudly made in Los Angeles.


With over 20 years in the diamond, estate and contemporary jewelry markets, we have built a network of relationships to source the most sought after jewelry, rare diamonds, and colored gemstones.


We maintain an open and collective relationship with designers, collaborators and clientele to create one of kind pieces for our store and to develop new collections for our clientele.


We are happy to evaluate both, contemporary and vintage jewelry for repair work and or value assessments. Appraisals for insurance purposes can be provided upon request.
