This 5.51ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844614449 or 844614449. Listed at 12 retailers as of October 30, 2026, with prices from $1,428 to $5,192, a $3,764 spread on the same certified stone. Taylor and Hart lists it at $5,192. 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.
