This 0.73ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG515228341 or 515228341. Listed at 18 retailers as of October 29, 2026, with prices from £101 to £969, a £868 spread on the same certified stone. Do Amore Diamonds lists it at £969. 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.
