About this 3.51ct natural round diamond

This 3.51ct natural round sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI 802609304. Listed at 12 retailers as of October 24, 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.
