About this 0.53ct lab-grown emerald diamond

This 0.53ct lab-grown emerald sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407944668 or 407944668. Listed at 11 retailers as of October 25, 2026, with prices from £212 to £1,055, a £843 spread on the same certified stone. MOH London lists it at £1,055. 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.
