About this 20.09ct lab-grown emerald diamond

This 20.09ct 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 LG849648390 or 849648390. Listed at 14 retailers as of November 2, 2026, with a 471% 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.
