About this 0.53ct natural round diamond

This 0.53ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6531088814. Listed at 29 retailers as of November 1, 2026, with a 176% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
