About this 1.26ct lab-grown emerald diamond

This 1.26ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6505414037. Listed at 4 retailers as of November 4, 2026, with prices from £561 to £958, a £397 spread on the same certified stone. Jared lists it at £958. 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.
