This 1.00 carat round brilliant cut diamond solitaire ring is set in a classic platinum mounting. The diamond is graded VS2 clarity and G color, offering a near-colorless appearance with only minor inclusions visible under 10x magnification. The round brilliant cut maximizes light return and sparkle, making it one of the most popular diamond shapes for engagement rings.
The ring comes with both GIA (Gemological Institute of America) and IGI (International Gemological Institute) certification, providing independent verification of the diamond's cut, clarity, color, and carat weight. The platinum setting is durable, hypoallergenic, and naturally white, ensuring the diamond's color is not influenced by the metal. Costco's diamond solitaire rings are known for their quality standards, with diamonds that meet strict criteria for cut grade and proportions.
