About this 3.01ct natural cushion diamond

This 3.01ct natural cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2557540580. Listed at 16 retailers as of November 5, 2026, with a relatively tight 3% spread, which is unusual at this carat range and suggests competitive pricing across the listings. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
