This platinum solitaire engagement ring features a 1.01 carat round brilliant cut diamond graded VS1 clarity and E color. The E color grade places this diamond in the "exceptional white" category, appearing virtually colorless to the naked eye. VS1 (Very Slightly Included 1) clarity means inclusions are minor and difficult to observe under 10x magnification.

The round brilliant cut is the most popular diamond shape, engineered with 57 or 58 facets to maximize light return and brilliance. Set in a classic platinum solitaire mounting, the design allows the diamond to be the focal point. Platinum provides a naturally white, hypoallergenic, and durable setting that will not fade or tarnish over time.
