This 10.55ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG652415751 or 652415751. Listed at 15 retailers as of October 29, 2026, with prices from $2,748 to $21,738, a $18,990 spread on the same certified stone. Brilliant Earth lists it at $21,738. 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.
