About this 0.8ct natural round diamond

This 0.8ct natural round sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2506352705. Listed at 21 retailers as of October 27, 2026, with a 196% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
