This 6.51ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG848645975 or 848645975. Listed at 11 retailers as of October 31, 2026, with prices from $5,261 to $19,415, a $14,154 spread on the same certified stone. Taylor and Hart lists it at $19,415. 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.
