This 1.70 carat cushion cut diamond solitaire ring is set in a platinum mounting and features a diamond graded VS1 clarity with G color. The cushion cut shape offers a classic, pillow-like silhouette with rounded corners and larger facets that enhance the diamond's brilliance and fire.
VS1 clarity indicates very slight inclusions that are difficult to see under 10x magnification, ensuring an eye-clean appearance. G color places the diamond in the near-colorless range, appearing white to the naked eye when mounted in the platinum setting. The platinum mounting provides a durable, hypoallergenic, and naturally white metal that will not tarnish or fade over time.
Costco diamond rings typically include a GIA grading report for diamonds of this size, verifying the cut, color, clarity, and carat weight. The ring comes with Costco's generous return policy for added peace of mind.
