About this 1.42ct lab-grown emerald diamond

This 1.42ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG844630758 or 844630758. Listed at 15 retailers as of November 4, 2026, with prices from £168 to £911, a £743 spread on the same certified stone. Brilliant Earth lists it at £911. 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.
