This stunning platinum three-stone engagement ring features a total diamond weight of 2.00 carats, with a prominent 0.90-carat round brilliant center stone flanked by two matching side stones. All diamonds are graded VS2 clarity, meaning inclusions are very slightly visible only under 10x magnification, and I color, which falls in the near-colorless range and appears bright white to the naked eye.
The ring is crafted in platinum, one of the rarest and most durable precious metals, prized for its natural white luster that will never fade or tarnish. Platinum's density and strength make it an ideal setting material for securing diamonds, and its hypoallergenic properties make it suitable for sensitive skin. The three-stone design is a timeless symbol of a couple's past, present, and future.
Costco's fine jewelry undergoes independent gemological certification, ensuring that each diamond meets the stated quality grades. This ring comes with an IGI or GIA certificate verifying the center stone's grading report.
