About this 0.52ct natural round diamond

This 0.52ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6435755535. Listed at 15 retailers as of October 30, 2026, with a 315% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
