About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA. Listed at 9 retailers as of November 4, 2026, with a relatively tight 21% 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.
