This classic Costco platinum diamond wedding band features 26 round brilliant-cut diamonds channel-set in a polished platinum shank. The 26 stones together total 0.36 carats in weight, graded I color (near-colorless) and VS2 clarity (very slightly included, eye-clean to the naked eye), offering an excellent balance of beauty and value.
Platinum is the most durable and prestigious precious metal used in fine jewelry, naturally white and hypoallergenic, making it an ideal choice for everyday wear. The channel setting secures each diamond flush within a continuous groove of metal, protecting the stones while delivering a smooth, snag-free band that wears comfortably alongside an engagement ring. This ring is sized 5, suitable for most women's ring fingers.
