This stunning platinum solitaire ring features a 1.50 carat cushion cut diamond with VS1 clarity and G color, offering exceptional brilliance and near-colorless beauty. The cushion cut diamond showcases a classic pillow shape with rounded corners and large facets that maximize light return and create a soft, romantic sparkle.
VS1 (Very Slightly Included 1) clarity means inclusions are minor and difficult to see under 10x magnification, ensuring a visually clean diamond to the naked eye. G color falls in the near-colorless range on the GIA scale, providing a bright white appearance at a more accessible price point than D-F colorless grades. The platinum setting provides a durable, naturally white metal that enhances the diamond's brilliance and is hypoallergenic.
Costco diamonds are independently certified by the Gemological Institute of America (GIA) and come with a diamond grading report. The ring is crafted with a classic four-prong or six-prong solitaire setting, allowing maximum light to enter the stone. Costco's fine jewelry carries a satisfaction guarantee and is available in a range of finger sizes.
