This elegant platinum ring features a 0.50-carat oval-cut center diamond complemented by round brilliant accent diamonds, totaling 1.39 carats total weight. The diamonds are graded VS2 clarity — meaning inclusions are very slight and invisible to the naked eye — and I color, which falls in the near-colorless range, delivering a bright and luminous appearance. The setting is crafted in platinum, a premium white metal prized for its density, durability, and naturally white luster that enhances diamond brilliance.
The oval center stone is framed by a pavé arrangement of round brilliant accent diamonds that amplify the visual size of the center stone and maximize the ring's overall sparkle. The elongated oval cut is widely admired for its flattering effect on the finger and its exceptional light performance. Platinum is one of the rarest precious metals and is highly hypoallergenic, making this ring an ideal choice for sensitive skin and long-term everyday wear.
Costco's diamond jewelry program requires all diamonds to meet VS2 or better clarity and I color or better standards. Diamonds sold by Costco typically include a GIA (Gemological Institute of America) Gem Trade Laboratory Diamond Grading Report, providing independent verification of the stone's quality. Model number: LVS1015OV.
