In-store pricing snapshot
Last known warehouse price ยท Jun 17, 2025. Currently out of stock.
* Prices shown are for Costco members only.
This platinum solitaire ring features a 1.19 carat round brilliant-cut diamond set in a classic four-prong platinum mounting. The center stone carries VS1 (Very Slightly Included 1) clarity, meaning inclusions are difficult to detect even under 10x magnification, and a G color grade, which falls in the near-colorless range for a bright, white appearance.
Platinum is the premium choice for fine diamond jewelry, offering exceptional durability, hypoallergenic properties, and a naturally white luster that will never fade or require rhodium replating. The round brilliant cut is the most popular diamond shape, renowned for its superior light performance and maximum sparkle with 57 or 58 facets optimized for brilliance, fire, and scintillation.
Costco diamond jewelry typically includes a GIA (Gemological Institute of America) grading report certifying the diamond's characteristics. All Costco diamonds are natural and untreated.
