About this 1.56ct lab-grown cushion diamond

This 1.56ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG639467029 or 639467029. Listed at 11 retailers as of October 25, 2026, with prices from £216 to £877, a £661 spread on the same certified stone. Brilliance lists it at £877. 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.
