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 SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2426532673. Listed at 29 retailers as of October 27, 2026, with a 192% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
