This elegant platinum ring features a stunning combination of round diamonds and princess-cut blue sapphires. The ring showcases 1.56 total carat weight of VS2 clarity diamonds in I color grade, complemented by vibrant blue sapphires measuring approximately 3 x 3.4 to 3.5 x 3.9 mm.
Crafted in premium platinum, this ring offers exceptional durability and a lustrous white finish that enhances the brilliance of both the diamonds and sapphires. VS2 clarity indicates very slight inclusions that are difficult to see under 10x magnification, while I color represents a near-colorless grade that appears white to the naked eye. The platinum setting provides a secure and elegant mounting for the gemstones.
This ring is sized at 5 and may be resizable within one size up or down, though Costco does not provide resizing services directly. The combination of round brilliant-cut diamonds and princess-cut sapphires creates a sophisticated contrast in both color and cut style. Each diamond and sapphire is carefully selected to meet Costco's quality standards for fine jewelry.
