About this 1.28ct lab-grown emerald diamond

This 1.28ct 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 LG831684177 or 831684177. Listed at 14 retailers as of November 1, 2026, with prices from $417 to $2,120, a $1,703 spread on the same certified stone. Reve Diamonds lists it at $2,120. 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.
