This 1.25-carat Round Brilliant solitaire ring features a natural, untreated diamond set in 950 platinum. The diamond carries a VVS2 (Very Very Slightly Included) clarity grade and I (Near Colorless) color grade, with an Excellent GIA cut grade that maximizes the stone's brilliance, fire, and light performance.

The ring is crafted in a timeless solitaire setting using 950 platinum, one of the most durable and prestigious metals used in fine jewelry. It comes standard in size 7 and can be professionally resized to any size by a jeweler of your choice. Costco does not provide resizing services.

Each ring is accompanied by a GIA (Gemological Institute of America) Diamond Grading Report and a Jewelry Grading/Gemological Report from an independent certified gemological laboratory, verifying the diamond's authenticity and characteristics as examined under 10x magnification. All diamonds offered are natural and untreated. This ring serves as an ideal engagement ring or fine jewelry gift and is recognized as an April birthstone piece.

Air shipping via insured UPS is included in the purchase price, with signature required upon delivery. For returns of items with a 1.00 ct or larger center diamond, Costco warehouses require 2-5 business days to verify the diamond with a Graduate Gemologist before a refund is approved.
