About this 3.09ct lab-grown emerald diamond

This 3.09ct lab-grown emerald sits in the three to five carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818652387 or 818652387. Listed at 8 retailers as of October 29, 2026, with prices from £1,543 to £5,339, a £3,796 spread on the same certified stone. Michael Trio lists it at £5,339. 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.
