A significant decision

See the Difference.

At four carats and above, cut, proportion, color, fluorescence, clarity, certification, and visual character all matter. A certificate is important, but it is not the whole story.

We Source

Expert guidance

Specialists Matter.

Afshin Shaddaie and Benjamin Khordipour have spent decades studying, sourcing, and evaluating important diamonds, antique jewelry, and exceptional estate pieces. Their work has been featured or quoted in Brides, CNBC, People, Rapaport, InStyle, and Business Insider.

For an important natural diamond, you should be able to discuss more than a grading report. We help clients assess beauty, rarity, and practical considerations together.
