This 0.87ct lab-grown emerald sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG528231950 or 528231950. Listed at 13 retailers as of October 25, 2026, with prices from £140 to £1,090, a £949 spread on the same certified stone. Do Amore Diamonds lists it at £1,090. 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.
