About this 0.99ct lab-grown emerald diamond

This 0.99ct lab-grown emerald sits in the just-under-one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831670277 or 831670277. Listed at 14 retailers as of October 26, 2026, with prices from £126 to £730, a £604 spread on the same certified stone. MOH London lists it at £730. 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.
