About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6521066268. Listed at 7 retailers as of November 3, 2026, with a relatively tight 22% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
