This classic platinum solitaire ring features a 1.80 carat round brilliant cut diamond set in a four or six-prong platinum mounting. The diamond carries VS2 (Very Slightly Included 2) clarity, meaning inclusions are minor and not visible to the naked eye, and I color, which falls in the near-colorless range for a clean, bright appearance at an excellent value.

Platinum is the premier metal choice for fine diamond jewelry, prized for its durability, natural white luster, and hypoallergenic properties. Unlike white gold, platinum does not require rhodium plating and maintains its appearance over time. Costco's diamond rings at this tier are accompanied by a GIA (Gemological Institute of America) diamond grading report, providing independent verification of the stone's carat weight, cut, color, and clarity grades.

The round brilliant cut is the most popular diamond shape, engineered with 57 or 58 facets to maximize light return, brilliance, and fire. A 1.80 carat round brilliant in VS2/I grades offers exceptional size and sparkle while remaining eye-clean and comparatively attainable relative to higher color grades.
