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 standard cut grade and certified by IGI LG842635109 or 842635109. Listed at 21 retailers as of October 28, 2026, with prices from £128 to £976, a £848 spread on the same certified stone. Do Amore Diamonds lists it at £976. 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.
