This 1.01ct 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 LG407988499 or 407988499. Listed at 10 retailers as of October 25, 2026, with prices from £541 to £2,969, a £2,428 spread on the same certified stone. MOH London lists it at £2,969. 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.
