This elegant platinum solitaire ring features a round brilliant-cut diamond with a total carat weight of 2.46 CTW, graded VS2 (Very Slightly Included 2) for clarity and I for color — placing it firmly in the near-colorless range. At this carat weight, Costco's diamond rings are accompanied by a GIA (Gemological Institute of America) certificate, providing independent verification of the stone's quality grades. The VS2 clarity grade means inclusions are minor and difficult to detect even under 10x magnification, making the diamond eye-clean to virtually all observers.

The setting is crafted in platinum (PT), a premium precious metal prized for its natural white luster, exceptional durability, and hypoallergenic properties. Platinum holds diamonds more securely than white gold and does not require rhodium plating to maintain its appearance over time. The ring is sized at 7, which is a common women's ring size and can typically be resized by a qualified jeweler.

Costco's in-house model number for this ring is CORB057U-7. As with all Costco fine diamond jewelry, this ring meets the retailer's strict minimum quality standards requiring VS2 or better clarity and I or better color, and is designed to offer exceptional value relative to traditional jewelry retailers.
