This 0.8ct natural round sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2487911155. Listed at 22 retailers as of November 4, 2026, with a 128% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
