About this 1.22ct lab-grown emerald diamond

This 1.22ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG821611444 or 821611444. Listed at 12 retailers as of November 1, 2026, with prices from £276 to £1,930, a £1,654 spread on the same certified stone. Brilliant Earth lists it at £1,930. 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.
