About this 1.66ct natural cushion diamond

This 1.66ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of October 31, 2026, with a relatively tight 10% 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.
