This Costco platinum solitaire ring features a 1.09 carat round brilliant cut diamond set in a classic four-prong platinum mounting. The diamond carries VVS2 (Very Very Slightly Included 2) clarity, one of the highest clarity grades available, meaning inclusions are extremely difficult to detect even under 10x magnification. The H color grade places the stone in the "near colorless" range, offering excellent visual whiteness and exceptional value relative to DโF colorless grades.
The ring is crafted in solid platinum (950 platinum), prized for its durability, natural white luster, and hypoallergenic properties. The simple solitaire design keeps the focus on the center stone and allows maximum light entry for optimal brilliance and fire. Costco's diamond jewelry is independently certified by the Gemological Institute of America (GIA), providing assurance of the diamond's stated specifications. This ring is ideal as an engagement ring or a significant gift for milestone occasions.
