About this 10.23ct natural round diamond

This 10.23ct natural round sits in the over five carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade and certified by GIA 1543595376. Listed at 17 retailers as of October 28, 2026, with a 35% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
