CENTER STONE
IGI-Certified Diamond, Always
The center stone in every ring is a D color / VVS / IGI certified lab-grown diamond. We email the certificate for your review before shipping — the color accents don't change this.
ACCENT STONES
Ruby, Blue Sapphire, or Pink Sapphire
Melee accents come in ruby, blue sapphire, or pink sapphire — chemically, physically, and visually identical to their natural counterparts, at Mohs 9 hardness.
GOLD OPTIONS
9K or 18K, Same Diamond Standard
Gold karat affects durability and price only — never the diamond grading or the accent stone quality.
AFTER-SALES

All finished rings include one year of complimentary repair, covering prong checks, polishing, and resizing.
Sidestone rings feature a 1.0ct VVS2 center diamond; half-eternity bands feature 0.05ct melee stones. Same price across ring sizes 9–13.
