About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG819653890 or 819653890. Listed at 8 retailers as of October 29, 2026, with prices from $532 to $1,460, a $928 spread on the same certified stone. MOH London lists it at $1,460. 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.
