About this 1.59ct lab-grown emerald diamond

This 1.59ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG617470290 or 617470290. Listed at 3 retailers as of October 30, 2026, with prices from £1,015 to £2,530, a £1,515 spread on the same certified stone. Kay Jewelers lists it at £2,530. 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.
