About this 6.5ct lab-grown cushion diamond

This 6.5ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG776688550 or 776688550. Listed at 18 retailers as of October 29, 2026, with prices from $2,126 to $11,441, a $9,315 spread on the same certified stone. Brilliant Earth lists it at $11,441. 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.
