This platinum halo engagement ring features a 1.00 ct round brilliant center diamond graded VS2 (Very Slightly Included) clarity and I color (Near Colorless), set in 950 platinum. A halo of accent diamonds surrounds the center stone, bringing the total diamond weight to 1.60 ctw across 27 natural diamonds.

The ring is crafted in 950 platinum for lasting durability and a bright, white finish that complements the diamond color grade. It comes in size 7 and is sizeable within one size (resizing is not provided by Costco). All diamonds offered by Costco are natural and untreated.

A jewelry grading and gemological report is included with purchase, providing independent verification of the center diamond's characteristics. Returns of items with a 1.00 ct center diamond or larger require gemological verification by a Costco Graduate Gemologist, a process that may take up to five business days.
