This classic solitaire ring features a 1.0 carat princess cut natural diamond set in a polished platinum band. The diamond carries a VS2 (Very Slightly Included) clarity grade and an I color grade, offering excellent brilliance with only minute inclusions invisible to the naked eye. Princess cut diamonds display a distinctive square brilliant shape with multiple facets that produce exceptional sparkle and light performance.
The ring is crafted in platinum, a naturally white precious metal that is denser and more durable than white gold, and will not fade or require re-plating over time. The princess cut stone is secured in a classic four-prong setting with V-shaped prongs designed to protect the sharp corners characteristic of this cut. Costco diamonds are natural and untreated, and this ring includes independent gemological certification verifying the diamond's grading.
