About this 1.03ct lab-grown emerald diamond

This 1.03ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG380972047 or 380972047. Listed at 8 retailers as of October 31, 2026, with prices from £455 to £1,761, a £1,305 spread on the same certified stone. NZ Jewellers lists it at £1,761. 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.
