This 1.23ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG818649681 or 818649681. Listed at 16 retailers as of October 25, 2026, with prices from £133 to £839, a £707 spread on the same certified stone. Reve Diamonds lists it at £839. 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.
