About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407981502 or 407981502. Listed at 10 retailers as of October 27, 2026, with prices from £533 to £2,940, a £2,407 spread on the same certified stone. MOH London lists it at £2,940. 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.
