This 1.00 carat round brilliant cut diamond solitaire ring is set in 950 platinum. The diamond is graded VVS2 clarity (Very Very Slightly Included) and H color (Near Colorless), offering exceptional brilliance with near-invisible inclusions even under 10x magnification.

The ring comes with a GIA (Gemological Institute of America) Diamond Grading Report and an independent Jewelry Grading/Gemological Report certifying the diamond's authenticity and characteristics. All Costco diamonds are natural and untreated. The ring is sizeable to any size, though Costco does not provide resizing services.

When returning jewelry items containing a 1.00 ct center diamond or larger, Costco warehouses require additional time for verification by a Graduate Gemologist, which may take up to five business days.
