This 1.58ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG849630423 or 849630423. Listed at 17 retailers as of November 1, 2026, with prices from £160 to £1,204, a £1,044 spread on the same certified stone. Rare Carat lists it at £1,204. 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.
