This platinum wedding ring features a 1.63 carat square emerald cut center diamond with VVS1 clarity and G color grading, set in a platinum band with additional accent diamonds for a total carat weight of 1.98 CTW. The square emerald cut, also known as an Asscher-style cut, showcases a distinctive step-cut faceting pattern that emphasizes the diamond's clarity and produces elegant flashes of light.

The center stone's VVS1 clarity grade indicates very, very slight inclusions that are extremely difficult to detect even under 10x magnification, ensuring exceptional transparency. The G color grade places the diamond in the near-colorless range, appearing white to the naked eye. The platinum setting provides a durable, naturally white metal that complements the diamond's brilliance without color interference.

Costco's diamond jewelry typically includes a GIA (Gemological Institute of America) grading report for independent verification of the diamond's quality characteristics. The total 1.98 CTW includes the center stone and accent diamonds set within the wedding ring design.
