This 1.54ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG623492391 or 623492391. Listed at 22 retailers as of November 4, 2026, with prices from £205 to £999, a £794 spread on the same certified stone. Reve Diamonds lists it at £999. 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.
