About this 0.8ct natural round diamond

This 0.8ct natural round sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 1543505054. Listed at 20 retailers as of October 28, 2026, with a 137% 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.
