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 30, 2026, with prices from $5,038 to $26,898, a $21,860 spread on the same certified stone. Adiamor lists it at $26,898. 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.
