This 10.23ct 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 LG728582016 or 728582016. Listed at 12 retailers as of October 31, 2026, with prices from $8,913 to $47,725, a $38,813 spread on the same certified stone. Adiamor lists it at $47,725. 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.
