This 10.52ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG816667447 or 816667447. Listed at 5 retailers as of October 30, 2026, with prices from £5,103 to £21,508, a £16,405 spread on the same certified stone. Adiamor lists it at £21,508. 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.
