This platinum solitaire engagement ring features a 1.32-carat round brilliant cut diamond with Internally Flawless (IF) clarity and I color grade. The diamond is set in a classic four-prong platinum setting that maximizes light performance and brilliance. IF clarity indicates the diamond has no inclusions visible under 10x magnification, placing it among the highest clarity grades available. The I color grade falls in the near-colorless range, offering excellent value while appearing white to the naked eye when mounted in platinum. Round brilliant cuts are the most popular diamond shape, optimized with 57 or 58 facets for maximum fire and scintillation.

Costco diamonds in this category typically come with an independent grading report from GIA or IGI and include a laser-inscribed registry number on the diamond's girdle for identification and security. The ring is sold with Costco's satisfaction guarantee and may be sized at purchase.
