This stunning platinum wedding ring features a 1.01 carat round brilliant center diamond with VS1 clarity and F color, placing it in the colorless range on the GIA grading scale. The total diamond weight of 1.73 carats includes additional round brilliant accent diamonds set throughout the platinum band, creating a brilliantly unified bridal look.
The center diamond's VS1 clarity grade means inclusions are very difficult to detect even under 10x magnification, ensuring exceptional brilliance and light performance. F color is among the finest on the GIA scale, falling in the colorless category (D–F), which means the diamond faces up with no detectable color to the naked eye. The ring is crafted in platinum, prized for its durability, natural white luster, and hypoallergenic properties, making it an ideal metal for fine diamond jewelry worn daily.
Costco's diamond rings of this caliber are accompanied by a GIA grading report for the center diamond, providing independent certification of the stone's quality characteristics.
