This stunning platinum solitaire ring features a 1.50 carat round brilliant cut diamond center stone graded VS2 (Very Slightly Included 2) in clarity and I in color, set in a classic four or six-prong solitaire mounting. The ring is crafted in platinum, one of the most durable and prestigious precious metals, known for its naturally white color that will never fade or tarnish. Available in size 7.
The round brilliant cut is the most popular and light-optimizing diamond shape, designed with 58 facets to maximize brilliance, fire, and scintillation. VS2 clarity indicates the diamond has very slight inclusions that are difficult to see even under 10x magnification, making it eye-clean to the naked eye. The I color grade falls in the near-colorless range, offering excellent value while maintaining a beautiful appearance when set in platinum.
Each Costco diamond ring comes with a GIA (Gemological Institute of America) grading report, providing independent certification of the diamond's quality characteristics. The ring arrives in elegant jewelry packaging, making it an ideal choice for engagements, anniversaries, or special occasions.
