About this 1.07ct lab-grown emerald diamond

This 1.07ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840631235 or 840631235. Listed at 8 retailers as of October 28, 2026, with prices from £462 to £1,535, a £1,073 spread on the same certified stone. Brilliant Earth lists it at £1,535. 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.
