About this 0.42ct lab-grown emerald diamond

This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG770699877 or 770699877. Listed at 19 retailers as of October 29, 2026, with prices from $316 to $2,803, a $2,488 spread on the same certified stone. Kay Jewelers lists it at $2,803. 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.
