About this 1.27ct lab-grown cushion diamond

This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830620288 or 830620288. Listed at 13 retailers as of October 30, 2026, with prices from $664 to $3,422, a $2,759 spread on the same certified stone. Brilliant Earth lists it at $3,422. 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.
