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 LG494175071 or 494175071. Listed at 2 retailers as of October 29, 2026, with prices from £329 to £689, a £360 spread on the same certified stone. B2C Jewels lists it at £689. 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.
