This 10.59ct 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 LG770612708 or 770612708. Listed at 13 retailers as of October 31, 2026, with prices from £3,875 to £21,467, a £17,592 spread on the same certified stone. Adiamor lists it at £21,467. 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.
