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 standard cut grade and certified by IGI LG723566709 or 723566709. Listed at 15 retailers as of November 1, 2026, with prices from $308 to $1,673, a $1,364 spread on the same certified stone. Reve Diamonds lists it at $1,673. 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.
