This Costco platinum solitaire ring features a 1.25 carat round brilliant cut diamond set in a classic four-prong or six-prong solitaire mounting crafted from platinum. The center stone carries VS2 (Very Slightly Included 2) clarity, indicating only minor inclusions not visible to the naked eye, and G color, which falls in the near-colorless range and appears bright white when set in platinum. Round brilliant diamonds are the most popular diamond shape, prized for their exceptional light performance and maximum sparkle.
Platinum is the premium precious metal choice for fine jewelry, offering superior durability, a naturally white luster that will never fade or require re-plating, and hypoallergenic properties. At approximately 95% pure platinum, this mounting provides lasting security for the center stone and pairs beautifully with the near-colorless G color grade. The VS2 clarity grade is highly desirable for its eye-clean appearance and excellent value relative to higher clarity grades.
This ring is suited as an engagement ring or fine jewelry statement piece. Costco's diamond jewelry typically includes a grading report from an independent gemological laboratory such as GIA or IGI, certifying the diamond's cut, color, clarity, and carat weight.
