About this 0.71ct lab-grown emerald diamond

This 0.71ct lab-grown emerald sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG551292852 or 551292852. Listed at 15 retailers as of November 2, 2026, with prices from £79 to £900, a £821 spread on the same certified stone. MOH London lists it at £900. 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.
