This 10.57ct 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 LG735559298 or 735559298. Listed at 13 retailers as of October 31, 2026, with prices from €4,639 to €25,651, a €21,012 spread on the same certified stone. Adiamor lists it at €25,651. 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.
