About this 1.22ct lab-grown emerald diamond

This 1.22ct lab-grown emerald sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG591399951 or 591399951. Listed at 13 retailers as of October 30, 2026, with prices from £138 to £1,187, a £1,049 spread on the same certified stone. Do Amore Diamonds lists it at £1,187. 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.
