About this 1.03ct lab-grown emerald diamond

This 1.03ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG739592661 or 739592661. Listed at 18 retailers as of November 4, 2026, with prices from £116 to £782, a £666 spread on the same certified stone. Reve Diamonds lists it at £782. 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.
