This 1.28ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG618498181 or 618498181. Listed at 15 retailers as of November 4, 2026, with prices from £276 to £1,304, a £1,028 spread on the same certified stone. Do Amore Diamonds lists it at £1,304. 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.
