About this 0.42ct lab-grown emerald diamond

This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816658329 or 816658329. Listed at 13 retailers as of October 26, 2026, with prices from £150 to £775, a £625 spread on the same certified stone. MOH London lists it at £775. 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.
