About this 20.04ct lab-grown emerald diamond

This 20.04ct lab-grown emerald sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821635716 or 821635716. Listed at 9 retailers as of October 31, 2026, with a 194% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
