About this 2.51ct lab-grown emerald diamond

This 2.51ct lab-grown emerald sits in the two to three carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG839616071 or 839616071. Listed at 13 retailers as of October 25, 2026, with a 269% 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.
