* Prices shown are for Costco members only.
This stunning solitaire pendant features a 1.20 carat round brilliant cut diamond set in a classic platinum mounting. The diamond is graded VS1 (Very Slightly Included 1) for clarity, meaning inclusions are difficult to detect even under 10x magnification, and H color, which falls in the near-colorless range and faces up white against the platinum setting.
Platinum is the premium choice for fine diamond jewelry, offering exceptional durability, a naturally white luster that will never fade or tarnish, and hypoallergenic properties. The round brilliant cut is the most popular diamond shape, engineered to maximize light return and brilliance through its 58 facets. Each Costco diamond pendant is accompanied by a diamond grading report from an independent gemological laboratory certifying the stone's characteristics.
