This 3.1ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG743580063 or 743580063. Listed at 8 retailers as of October 29, 2026, with prices from $1,819 to $12,935, a $11,116 spread on the same certified stone. Brilliant Earth lists it at $12,935. 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.
