About this 6.53ct lab-grown cushion diamond

This 6.53ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG830661964 or 830661964. Listed at 14 retailers as of October 31, 2026, with prices from $1,446 to $6,614, a $5,168 spread on the same certified stone. Blue Nile lists it at $6,614. 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.
