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 October 30, 2026, with prices from £243 to £2,187, a £1,944 spread on the same certified stone. Brilliant Earth lists it at £2,187. 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.
