A 1.02 carat round brilliant cut diamond solitaire ring set in platinum. This diamond is graded VS1 clarity and E color, placing it in the near-colorless to colorless range with very slight inclusions that are difficult to detect under 10x magnification. The round brilliant cut maximizes light performance and sparkle, making it the most popular diamond shape for engagement rings.

Costco's diamond rings in this category typically come with a GIA grading report or gemological documentation verifying the diamond's specifications. The platinum setting provides a durable, hypoallergenic precious metal that complements the diamond's brilliance. Costco requires diamonds in their inventory to meet minimum standards of VS2 clarity and I color, making this VS1/E combination above their baseline quality threshold.
