About this 0.91ct lab-grown emerald diamond

This 0.91ct lab-grown emerald sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG10121605 or 10121605. Listed at 6 retailers as of October 30, 2026, with prices from £215 to £587, a £372 spread on the same certified stone. The Diamond Guys lists it at £587. 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.
