About this 1.21ct lab-grown emerald diamond

This 1.21ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG615378726 or 615378726. Listed at 17 retailers as of October 28, 2026, with prices from £192 to £914, a £722 spread on the same certified stone. Reve Diamonds lists it at £914. 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.
