This 1.13ct natural round sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2426727779. Listed at 13 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.
