About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2527883496. Listed at 19 retailers as of November 5, 2026, with a 96% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
