About this 0.52ct natural round diamond

This 0.52ct natural round sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2537434310. Listed at 15 retailers as of November 4, 2026, with a 214% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
