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 VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG844612518 or 844612518. Listed at 7 retailers as of October 29, 2026, with prices from $520 to $1,643, a $1,123 spread on the same certified stone. Michael Trio lists it at $1,643. 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.
