About this 1.23ct lab-grown emerald diamond

This 1.23ct lab-grown emerald sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG687541963 or 687541963. Listed at 2 retailers as of October 30, 2026, with prices from £760 to £931, a £171 spread on the same certified stone. Jared lists it at £931. 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.
