About this 20.21ct natural emerald diamond
This 20.21ct natural emerald sits in the over five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5211914064. Listed at 3 retailers as of October 28, 2026, with prices from €518,132 to €617,091, a €98,959 spread on the same certified stone. Blue Nile lists it at €617,091. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
