About this 0.55ct natural round diamond

This 0.55ct natural round sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 2556242216. Listed at 15 retailers as of November 2, 2026, with a 170% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
