About this 0.91ct lab-grown emerald diamond

This 0.91ct lab-grown emerald sits in the just-under-one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG502117946 or 502117946. Listed at 14 retailers as of October 26, 2026, with prices from £110 to £710, a £599 spread on the same certified stone. MOH London lists it at £710. 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.
