About this 0.8ct natural round diamond

This 0.8ct natural round sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6545790566. Listed at 21 retailers as of October 29, 2026, with a 147% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
