About this 0.7ct lab-grown emerald diamond

This 0.7ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG551299311 or 551299311. Listed at 15 retailers as of October 27, 2026, with prices from £86 to £987, a £901 spread on the same certified stone. MOH London lists it at £987. 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.
