About this 1.53ct natural round diamond

This 1.53ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 3525486689. Listed at 12 retailers as of October 29, 2026, with a 111% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
