This stunning platinum ring features a 1.39 carat cushion cut center diamond graded Fancy Intense Yellow, one of the most vivid and sought-after natural color grades in diamond classification. The total diamond weight of 1.85 carats (CTW) encompasses the center stone along with accent diamonds set into the platinum band, creating a rich, luminous composition.
The cushion cut shape combines a square or rectangular outline with softly rounded corners and large facets that maximize brilliance and color saturation โ particularly effective for showcasing the warm golden hue of a Fancy Intense Yellow diamond. The VS2 clarity grade (decoded from the SKU) indicates very slight inclusions that are not visible to the naked eye, ensuring a clean, bright appearance.
Platinum is the most durable and hypoallergenic precious metal used in fine jewelry, offering a naturally white luster that will not fade or tarnish over time. This ring is suited as an engagement ring, anniversary gift, or statement piece for collectors of natural color diamonds. Costco's fine jewelry undergoes independent gemological grading, and the ring comes with a grading report from an accredited gemological laboratory.
