About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6512809804. Listed at 7 retailers as of November 5, 2026, with a relatively tight 20% 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.
