About this 0.9ct lab-grown emerald diamond

This 0.9ct lab-grown emerald sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG754584751 or 754584751. Listed at 10 retailers as of October 28, 2026, with prices from £89 to £353, a £264 spread on the same certified stone. NZ Jewellers lists it at £353. 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.
