About this 1.99ct lab-grown emerald diamond

This 1.99ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG539235328 or 539235328. Listed at 15 retailers as of November 6, 2026, with prices from £128 to £1,128, a £1,000 spread on the same certified stone. Michael Trio lists it at £1,128. 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.
