About this 1.9ct lab-grown emerald diamond

This 1.9ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG464107525 or 464107525. Listed at 13 retailers as of October 28, 2026, with prices from £140 to £1,025, a £885 spread on the same certified stone. Rare Carat lists it at £1,025. 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.
