This 20.13ct 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 LG705513520 or 705513520. Listed at 12 retailers as of October 31, 2026, with prices from $13,180 to $65,064, a $51,884 spread on the same certified stone. Brilliant Earth lists it at $65,064. 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.
