About this 20.05ct natural emerald diamond

This 20.05ct natural emerald sits in the over five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6237596110. Listed at 8 retailers as of October 30, 2026, with prices from £615,722 to £943,077, a £327,355 spread on the same certified stone. Aurelinne lists it at £943,077. 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.
