About this 1.37ct lab-grown emerald diamond

This 1.37ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762546355 or 762546355. Listed at 14 retailers as of October 29, 2026, with prices from £302 to £1,456, a £1,154 spread on the same certified stone. Blue Nile lists it at £1,456. 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.
