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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG849637309 or 849637309. Listed at 7 retailers as of November 5, 2026, with prices from £94 to £291, a £198 spread on the same certified stone. Michael Trio lists it at £291. 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.
