About this 15.56ct lab-grown emerald diamond

This 15.56ct lab-grown emerald sits in the over five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG596344307 or 596344307. Listed at 13 retailers as of October 30, 2026, with prices from £1,669 to £10,068, a £8,399 spread on the same certified stone. Brilliant Earth lists it at £10,068. 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.
