This stunning solitaire ring features a 1.00 carat round brilliant cut diamond set in a classic platinum band. The diamond is graded VVS1 (Very Very Slightly Included, Grade 1) clarity — one of the highest clarity grades available — meaning inclusions are extremely difficult to detect even under 10x magnification. The G color grade places this diamond in the near-colorless range, offering exceptional brilliance with no discernible color to the unaided eye.
The solitaire setting showcases the diamond as the centerpiece, allowing maximum light performance and fire. Platinum is the most durable and prestigious precious metal used in fine jewelry, naturally white, hypoallergenic, and resistant to tarnish. Costco's fine diamond jewelry typically includes GIA (Gemological Institute of America) certification and an independent diamond grading report, ensuring authenticity and quality assurance.
