About this 1.08ct lab-grown emerald diamond

This 1.08ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG831638203 or 831638203. Listed at 7 retailers as of November 2, 2026, with prices from £238 to £647, a £410 spread on the same certified stone. MOH London lists it at £647. 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.
