About this 0.82ct lab-grown emerald diamond

This 0.82ct lab-grown emerald sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407950374 or 407950374. Listed at 10 retailers as of November 1, 2026, with prices from £315 to £1,436, a £1,121 spread on the same certified stone. MOH London lists it at £1,436. 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.
