About this 3.09ct lab-grown emerald diamond

This 3.09ct lab-grown emerald sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835607391 or 835607391. Listed at 21 retailers as of November 4, 2026, with a 302% 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.
