About this 0.31ct lab-grown emerald diamond

This 0.31ct lab-grown emerald sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG662408821 or 662408821. Listed at 16 retailers as of October 25, 2026, with prices from £131 to £837, a £707 spread on the same certified stone. MOH London lists it at £837. 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.
