About this 1.5ct lab-grown emerald diamond

This 1.5ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG570363621 or 570363621. Listed at 12 retailers as of November 2, 2026, with prices from £126 to £728, a £603 spread on the same certified stone. MOH London lists it at £728. 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.
