This 1.00 carat round brilliant cut diamond solitaire ring is set in a platinum band. The diamond is graded VS1 clarity, meaning it has very slight inclusions that are difficult to see under 10x magnification, and H color, placing it in the near-colorless range on the GIA color scale. Round brilliant is the most popular diamond shape, known for its exceptional light performance and sparkle due to its 57 or 58 precisely angled facets.
The platinum setting provides a durable, naturally white metal that will not fade or tarnish over time, complementing the diamond's brilliance. Costco diamonds come with a GIA or IGI grading report, and Costco offers a satisfaction guarantee on all jewelry purchases. Each diamond is individually inspected to meet Costco's quality standards before being set and sold.
