About this 0.52ct natural round diamond

This 0.52ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 1499380789. Listed at 12 retailers as of November 1, 2026, with a 155% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
