About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG800644001 or 800644001. Listed at 8 retailers as of November 1, 2026, with prices from £110 to £1,033, a £923 spread on the same certified stone. MOH London lists it at £1,033. 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.
