The Gemstone Vault: Rare Natural Diamonds & Sapphires

Welcome to a hand-curated showcase of rare natural earth-mined diamonds and fancy sapphires, available on-demand for private in-person viewing at our Brookline shop.

Initial stone inquiries and project estimates are complimentary with zero obligation. To bring a specific partner vault gem to our shop for a private 7-day viewing window, a $500 Vault Sourcing & Design Deposit holds your stone, begins your custom 3D CAD design, and applies 100% toward your finished ring balance.
