About this 5.09ct lab-grown emerald diamond

This 5.09ct lab-grown emerald sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762544692 or 762544692. Listed at 15 retailers as of October 31, 2026, with prices from £4,962 to £20,770, a £15,808 spread on the same certified stone. Taylor and Hart lists it at £20,770. 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.
