* Prices shown are for Costco members only.
This platinum wedding set features a stunning round brilliant-cut center diamond weighing 1.15 carats, set in a classic solitaire engagement ring paired with a matching diamond-studded wedding band. The total diamond weight across the complete set is 1.90 carats, offering exceptional sparkle and brilliance from every angle.
The center diamond is graded VS1 (Very Slightly Included) for clarity and "I" color, meaning it is nearly eye-clean with only minute inclusions invisible to the naked eye. The mounting is crafted in platinum (950), a premium precious metal prized for its durability, hypoallergenic properties, and naturally white luster that will never fade or require replating. The engagement ring and matching band are designed to nest perfectly together for a seamless, polished look.
Costco jewelry typically includes a diamond grading or appraisal certificate. Costco's generous return policy applies to jewelry purchases.
