About this 0.42ct lab-grown emerald diamond

This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG662408840 or 662408840. Listed at 21 retailers as of November 1, 2026, with prices from $204 to $1,105, a $901 spread on the same certified stone. MOH London lists it at $1,105. 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.
