This elegant solitaire engagement ring features a 1.03 carat round brilliant cut natural diamond set in a classic platinum mounting. The diamond is graded VVS2 clarity (Very Very Slightly Included), meaning inclusions are extremely difficult to detect even under 10x magnification, and G color, which falls in the near-colorless range and faces up bright white to the naked eye.
The platinum setting provides a naturally white, hypoallergenic, and highly durable metal that complements the diamond's brilliance. Platinum is denser and more rare than white gold, making it an ideal choice for a ring intended for everyday wear. The solitaire design keeps the focus entirely on the center stone, allowing the diamond's exceptional cut, clarity, and color to take center stage.
This ring is consistent with Costco's fine jewelry line, which typically includes GIA or IGI laboratory grading reports verifying the diamond's specifications. The round brilliant cut is the most popular diamond shape, prized for its fire, scintillation, and light performance.
