About this 5.51ct natural round diamond

This 5.51ct natural round sits in the over five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI 819634321. Listed at 3 retailers as of November 3, 2026, with a relatively tight 10% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
