About this 0.7ct lab-grown emerald diamond

This 0.7ct lab-grown emerald sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG476160105 or 476160105. Listed at 2 retailers as of October 29, 2026, with prices from £267 to £313, a £45 spread on the same certified stone. MD Diamonds and Jewellers lists it at £313. 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.
