This 1.23ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG655451961 or 655451961. Listed at 5 retailers as of November 1, 2026, with prices from $221 to $1,790, a $1,569 spread on the same certified stone. Do Amore Diamonds lists it at $1,790. 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.
