About this 1.71ct lab-grown emerald diamond

This 1.71ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG594313064 or 594313064. Listed at 5 retailers as of October 26, 2026, with prices from £375 to £982, a £608 spread on the same certified stone. MOH London lists it at £982. 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.
