About this 18.08ct lab-grown emerald diamond

This 18.08ct 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 LG728566006 or 728566006. Listed at 15 retailers as of October 30, 2026, with a 432% 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.
