This 1.2ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG574346195 or 574346195. Listed at 13 retailers as of October 30, 2026, with prices from $485 to $3,089, a $2,604 spread on the same certified stone. Do Amore Diamonds lists it at $3,089. 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.
