About this 6.51ct lab-grown cushion diamond

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 very-good cut grade and certified by IGI LG787666382 or 787666382. Listed at 10 retailers as of October 31, 2026, with prices from $3,314 to $11,039, a $7,725 spread on the same certified stone. Taylor and Hart lists it at $11,039. 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.
