About this 5.16ct natural cushion diamond

This 5.16ct natural cushion sits in the over five carat band, graded E 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 2225927620. Listed at 2 retailers as of October 31, 2026, with a relatively tight 2% 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.
