About this 1.31ct lab-grown emerald diamond

This 1.31ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653934 or 818653934. Listed at 19 retailers as of November 4, 2026, with a 770% 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.
