About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 7502721872. Listed at 19 retailers as of November 2, 2026, with a 228% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
