This 1.88ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818681090 or 818681090. Listed at 5 retailers as of October 28, 2026, with prices from £2,549 to £4,483, a £1,934 spread on the same certified stone. Brilliant Earth lists it at £4,483. 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.
