Cartesian
Cartesian is a one of a kind ring. The proportions had to be perfect. My team and I spent countless hours matching the perfect curve with the right diamond dimensions. The knife edge band blends seamlessly into the union of the two diamonds.

RESPONSIBLY SOURCED
All ILA diamonds & gemstones are responsibly sourced — and also pre-screened by a diamond expert, since certificates don’t have the whole story. We check each one individually, so that you’ll always get a top tier diamond with the highest cut grade.
