This Costco platinum solitaire ring features a 1.03-carat round brilliant cut diamond with VS2 clarity and I color grading, set in a classic four-prong platinum solitaire mounting. The round brilliant cut is the most popular diamond shape, prized for its exceptional light performance and fire — 58 precisely angled facets maximize brilliance and sparkle.

VS2 (Very Slightly Included 2) clarity indicates that inclusions are minor and not visible to the naked eye, ensuring a clean, beautiful appearance. I color falls in the near-colorless range on the GIA scale, offering an excellent balance of quality and value while appearing white in most lighting conditions and settings. Platinum is the most durable and prestigious metal for fine jewelry, naturally white and hypoallergenic, and its density helps secure the diamond safely over a lifetime of wear.

Costco's diamond rings at this tier typically include a GIA grading report, providing independent third-party certification of the diamond's specifications. The solitaire setting is a timeless, versatile design that pairs beautifully with a variety of wedding bands.
