This Costco platinum wedding set features a 1.50 carat round brilliant center diamond paired with a matching diamond band, totaling 2.22 carats total weight. The center stone is graded VS1 (Very Slightly Included) for clarity and H color, placing it in the near-colorless range that appears white to the naked eye. The setting is crafted in platinum, the most durable and prestigious precious metal for fine jewelry, prized for its natural white luster and hypoallergenic properties.

The round brilliant cut is the most popular diamond shape, engineered to maximize light reflection and brilliance. VS1 clarity means inclusions are minor and not visible to the unaided eye, ensuring a visually clean stone. H color diamonds offer an excellent balance of near-colorless appearance and value. Costco's fine jewelry typically includes a GIA gemological grading report providing independent certification of the diamond's specifications. The set is designed so the engagement ring and wedding band nest together seamlessly.
