About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6551054088. Listed at 23 retailers as of November 4, 2026, with a 131% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
