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 5516093517. Listed at 18 retailers as of October 27, 2026, with a 356% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
