The Osiris Ideal™ Cut Standard
My personal benchmark for diamonds that actually light up in real life.
The truth about “Ideal” diamonds? The range is incredibly wide—meaning a dull stone and a breathtaking one can carry the same grade. I created Osiris Ideal™ to distinguish diamonds that meet my tighter standards for proportions and real-world visual performance.
Diamonds personally selected for The Osiris Diamond Vault are reviewed beyond the certificate before receiving the Osiris Ideal™ designation.
