This platinum bridal wedding set features a cushion cut center diamond of 1.20 carats with VS1 (Very Slightly Included) clarity and I color grade, totaling 1.81 carats total weight across the engagement ring and matching wedding band. The cushion cut is a classic shape with rounded corners and large facets that enhance the diamond's brilliance and fire.

The setting is crafted in platinum, a premium precious metal prized for its durability, natural white luster, and hypoallergenic properties. Platinum holds diamonds more securely than white gold and maintains its finish over time without replating. The VS1 clarity grade means the diamond has very minor inclusions that are difficult to see even under 10x magnification, while the I color grade falls in the near-colorless range with slight warmth visible to a trained eye.

Costco's diamond jewelry typically includes a GIA (Gemological Institute of America) Diamond Grading Report, certifying the center stone's cut, color, clarity, and carat weight. The set ships pre-assembled as a matched engagement ring and contoured wedding band designed to sit flush together.
