This stunning solitaire ring features a 1.50 carat round brilliant cut diamond set in a classic platinum band. The diamond is graded VS2 (Very Slightly Included 2) for clarity and I color, representing a near-colorless stone with only minute inclusions that are difficult to detect even under 10x magnification.
The ring is crafted in platinum, a naturally white precious metal prized for its durability, density, and hypoallergenic properties. Platinum's bright white luster perfectly complements the sparkle of the round brilliant diamond, which is the most popular diamond cut due to its exceptional light performance and fire. The solitaire setting places all focus on the center stone, allowing it to showcase its full brilliance.
Ring is sized 7. Costco diamonds are natural and untreated. A GIA (Gemological Institute of America) grading report is typically included with Costco diamond solitaire rings of this caliber, providing independent certification of the diamond's specifications.
