About this 1.2ct lab-grown emerald diamond

This 1.2ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG616410831 or 616410831. Listed at 14 retailers as of October 29, 2026, with prices from £144 to £839, a £695 spread on the same certified stone. MOH London lists it at £839. 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.
