About Us

Our Story

Established in 1985, SFD is the leading diamond importer and wholesaler in San Francisco, CA. The company is proudly owned and operated by the Raz family. After graduating from McGill University (Canada), Karen apprenticed at the diamond exchange in Ramat Gan, Israel, where she gained her expertise working with the finest masters. It’s there where she met Ami. The two fell in love, got married, and decided to come to America to share their life and dreams together… and the rest is history!

We provide loose diamonds to diamond dealers, jewelry stores, and manufacturers across the US. For over 20 years, we have imported from around the world to bring our customers the best selection at the most affordable prices. Each of our customers is part of our SFD family. Whatever your needs – from melee to matched pairs and certified to non-certified diamonds in all shapes and sizes – we are here to help."
