This 1.23ct 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 LG596324746 or 596324746. Listed at 4 retailers as of October 31, 2026, with prices from $1,678 to $2,354, a $676 spread on the same certified stone. Zales lists it at $2,354. 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.
