About this 0.81ct natural round diamond

This 0.81ct natural round sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6237610744. Listed at 13 retailers as of October 28, 2026, with a 152% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
