This 10.21ct 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 LG728582015 or 728582015. Listed at 12 retailers as of November 2, 2026, with prices from $8,910 to $47,625, a $38,714 spread on the same certified stone. Adiamor lists it at $47,625. 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.
