About this 1.27ct lab-grown emerald diamond

This 1.27ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830623278 or 830623278. Listed at 18 retailers as of October 30, 2026, with prices from $500 to $4,652, a $4,152 spread on the same certified stone. Brilliant Earth lists it at $4,652. 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.
