About this 1.28ct lab-grown emerald diamond

This 1.28ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG605351171 or 605351171. Listed at 14 retailers as of October 29, 2026, with prices from £163 to £971, a £808 spread on the same certified stone. Taylor and Hart lists it at £971. 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.
