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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG769621492 or 769621492. Listed at 4 retailers as of October 30, 2026, with prices from $707 to $990, a $283 spread on the same certified stone. Kay Jewelers lists it at $990. 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.
