This platinum diamond pendant features a 1.20 carat round brilliant cut diamond set in a classic solitaire style. The diamond is graded VS1 (Very Slightly Included) for clarity, indicating only minute inclusions that are difficult to see even under 10x magnification, and H color, which falls in the near-colorless range and appears virtually colorless to the naked eye.

The pendant is set in platinum, a premium precious metal prized for its durability, natural white luster, and hypoallergenic properties. Platinum holds diamonds more securely than white gold and does not require rhodium plating to maintain its bright finish. Costco diamond jewelry of this grade typically includes a GIA (Gemological Institute of America) grading report or equivalent third-party certification, providing independent verification of the diamond's specifications.

The round brilliant cut is the most popular diamond shape, renowned for its exceptional light performance and maximum sparkle due to its 58 precisely angled facets. A 1.20 carat center stone delivers a substantial presence suitable for an everyday fine jewelry piece or a special occasion gift.
