About this 1.04ct lab-grown emerald diamond

This 1.04ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG488128314 or 488128314. Listed at 14 retailers as of November 1, 2026, with prices from £100 to £1,032, a £933 spread on the same certified stone. MOH London lists it at £1,032. 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.
