This stunning platinum ring features a 1.04 carat round brilliant-cut center diamond of exceptional VS1 clarity and G color — a near-colorless, eye-clean stone with only minor inclusions invisible to the naked eye. The center diamond is flanked by two baguette-cut accent diamonds, bringing the total carat weight to 1.36 CTW.
The ring is crafted in platinum, offering a naturally white luster that enhances the brilliance of the diamonds while providing superior durability and hypoallergenic properties. VS1 clarity indicates very slight inclusions that are difficult to see under 10x magnification and completely invisible to the unaided eye. G color falls in the near-colorless range, appearing white to the naked eye and offering excellent value compared to the colorless (D–F) range.
Costco diamonds are certified by independent gemological laboratories, ensuring the specifications represent verified quality standards. This ring is well-suited as an engagement ring or special-occasion jewelry piece.
