This 1.2ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2554750922. Listed at 21 retailers as of November 4, 2026, with a 139% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
