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 exact same grade. I created the Osiris Ideal™ to cut through that confusion.
For each shape, I use tight proportion ranges and real-world visual checks to keep only the topperforming stones. If a diamond doesn’t hit that sweet spot for light return and sparkle, it never gets listed.
I’ve helped thousands of people find their diamond. What I learned: most shoppers are overwhelmed by giant online lists—good and bad stones all blended together.
So I removed the Guesswork and created the Osiris Ideal™ standard — my own cut criteria that sits inside the “Excellent” range and focuses only on top light performance. If a diamond doesn’t meet Osiris Ideal™, it never makes it onto the site.
Fewer options. Better options. No second-guessing.
