About this 1.28ct lab-grown cushion diamond

This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830658262 or 830658262. Listed at 16 retailers as of November 1, 2026, with prices from $316 to $1,970, a $1,654 spread on the same certified stone. Michael Trio lists it at $1,970. 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.
