Facts you can depend on.
Every stone comes with an independent IGI report which records identifying details like measurements, carat weight, color, clarity, finish, and cut grade where it applies. Axiom only offers colorless (D to F) white diamonds that are "eye-clean," meaning any inclusions generally can't be seen with the naked eye, so your stone will look great no matter which one you choose.
Excellent is just the beginning.
The 4Cs will tell you what a diamond is, but cut, polish, and symmetry together decide how it actually performs. That's why we only offer Triple Excellent stones. Every diamond is screened to that standard by expert gemologists before it reaches our collection, so each one returns light the way a diamond should. Learn how to read a diamond’s grades in our 4Cs guide.
One standard across every shape. Excellent cut quality is one of the 4Cs we select for, sometimes labeled "ideal cut," but we don't just stop there. Our gemologists also ensure every diamond we carry has excellent polish and symmetry as well, since those are what separate a good diamond from a truly excellent one.
Know the number.
Choose the details of the diamond your jewelry store offered you. We'll show the estimated price to get your diamond from us vs a retail store and the estimated cost to have the diamond mounted separately, so you know just how much you could be saving.
