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 G colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG651420560 or 651420560. Listed at 3 retailers as of October 30, 2026, with prices from £716 to £970, a £254 spread on the same certified stone. Jared lists it at £970. 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.
