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 LG840629726 or 840629726. Listed at 15 retailers as of November 1, 2026, with prices from $295 to $2,206, a $1,911 spread on the same certified stone. Helzberg Diamonds lists it at $2,206. 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.
