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 IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830614534 or 830614534. Listed at 11 retailers as of November 1, 2026, with prices from €285 to €1,694, a €1,409 spread on the same certified stone. Brilliant Earth lists it at €1,694. 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.
