This 3.51ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG768694885 or 768694885. Listed at 18 retailers as of October 31, 2026, with prices from $1,606 to $9,084, a $7,479 spread on the same certified stone. Brilliant Earth lists it at $9,084. 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.
