This 1.51ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831697435 or 831697435. Listed at 5 retailers as of October 30, 2026, with prices from £978 to £3,490, a £2,511 spread on the same certified stone. Taylor and Hart lists it at £3,490. 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.
