This Costco platinum wedding set features a 1.98 carats total weight (CTW) of round brilliant-cut diamonds, with a 1.21 carat center stone graded VS1 clarity and H color. The set is crafted in platinum, a premium precious metal prized for its durability, density, and naturally white luster that will not fade or tarnish over time.
The center diamond displays VS1 clarity, meaning inclusions are very difficult to detect even under 10x magnification, resulting in an eye-clean appearance. The H color grade places the stone in the "near colorless" range, appearing white to the naked eye when set in platinum. The round brilliant cut is the most popular diamond shape, engineered to maximize light return and brilliance through its 57 or 58 facets.
The wedding set typically includes both an engagement ring and a matching wedding band designed to nestle together seamlessly. The total diamond weight of 1.98 CTW includes the center stone plus the accent or side diamonds set along the band. Platinum construction provides a hypoallergenic setting that is ideal for sensitive skin and holds diamonds securely due to its high density.
