About this 0.5ct natural round diamond

This 0.5ct natural round sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 7406674657. Listed at 23 retailers as of November 6, 2026, with a 193% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
