This 1.4ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG615371048 or 615371048. Listed at 4 retailers as of November 4, 2026, with prices from £974 to £1,333, a £359 spread on the same certified stone. Kay Jewelers lists it at £1,333. 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.
