This stunning platinum 3-row diamond band features 36 round brilliant-cut natural diamonds with a combined total weight of 3.00 carats, elegantly set in a three-row configuration across a polished platinum shank. Each diamond is graded VS2 clarity (Very Slightly Included) and I color (Near Colorless), delivering exceptional brilliance and a near-colorless appearance at outstanding Costco value.

Crafted in platinum — a naturally white, dense, and durable precious metal — the band offers long-lasting wearability while enhancing the fire and sparkle of its diamonds. The low-profile three-row setting delivers impressive diamond coverage and is comfortable enough for everyday wear. Customers consistently praise the ring's substantial, quality weight and extraordinary sparkle, with one independent appraisal valuing the ring at $11,000.
