About this 0.73ct natural radiant diamond

This 0.73ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2185412499. Listed at 3 retailers as of November 4, 2026, with a relatively tight 5% 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.
