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 LG821651498 or 821651498. Listed at 11 retailers as of November 4, 2026, with prices from $366 to $1,895, a $1,529 spread on the same certified stone. MOH London lists it at $1,895. 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.
