About this 1.59ct lab-grown emerald diamond

This 1.59ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6501820114. Listed at 13 retailers as of October 26, 2026, with prices from £304 to £1,318, a £1,014 spread on the same certified stone. MOH London lists it at £1,318. 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.
