About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG834609843 or 834609843. Listed at 13 retailers as of October 31, 2026, with prices from $397 to $2,683, a $2,286 spread on the same certified stone. Brilliant Earth lists it at $2,683. 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.
