About this 0.5ct lab-grown emerald diamond

This 0.5ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616819 or 778616819. Listed at 11 retailers as of October 28, 2026, with prices from $252 to $804, a $552 spread on the same certified stone. MOH London lists it at $804. 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.
