This elegant platinum diamond ring features a 0.23 carat round brilliant center diamond, surrounded by accent diamonds totaling 0.50 carats combined weight. The diamonds are graded VS2 clarity (Very Slightly Included), meaning inclusions are extremely difficult to detect even under 10x magnification, and I color, placing them in the near-colorless range for a bright, brilliant appearance.
The ring is crafted in platinum, one of the most durable and naturally white precious metals, offering exceptional resistance to wear and tarnish while securely holding the diamonds over a lifetime. The round brilliant cut is the most popular diamond shape, designed with 58 facets to maximize light return and sparkle. Model RGR28404 is sized at 7 and includes a Certificate of Authenticity and original packaging from Costco.
