The Irdoja standard

Every diamond, held to one standard.

We aim for E or F color, VVS2 clarity and an Excellent cut. The grade on your piece is whatever its own report says, and the product page states it. Natural centers over 0.30 ct arrive with a GIA report; lab-grown center stones over 0.50 ct with an IGI report. Every piece is handcrafted to order, and the report travels with the finished piece.
