This 10.37ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG735559301 or 735559301. Listed at 13 retailers as of October 30, 2026, with prices from £3,809 to £20,610, a £16,801 spread on the same certified stone. Adiamor lists it at £20,610. 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.
