About this 1.03ct natural round diamond

This 1.03ct natural round sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 1493000926. Listed at 13 retailers as of November 4, 2026, with a 95% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
