FULL ETERNITY
Diamonds All the Way Around
Sparkle from every angle. Because a full circle needs more diamonds as the ring gets bigger, price rises slightly with ring size — this is the one style where that happens.
HALF ETERNITY
Diamonds Across the Top, Flat Underneath
More comfortable for everyday wear and stacking with other rings. Same diamond count regardless of finger size, so the price stays the same across sizes 9–13.
GRADING STANDARD
D-E-F Color, VS-VVS Clarity, MISI™-Verified
At this melee size (1.5mm–3mm, well under 1ct), cut precision can't be reliably verified stone-by-stone, so we grade each diamond D-E-F color and VS-VVS clarity in-house against our MISI™ sparkle index. Individual IGI certification and 3EX cut grading are reserved for center stones 1ct and above.
AFTER-SALES
1-Year Complimentary Repair
All finished eternity bands include one year of complimentary repair, covering prong checks, polishing, and resizing.
Full eternity prices shown are for size 9; expect a small increase at larger sizes. Half eternity is the same price at any size.
