This 1.52ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG497180542 or 497180542. Listed at 12 retailers as of November 6, 2026, with prices from $247 to $2,400, a $2,153 spread on the same certified stone. Do Amore Diamonds lists it at $2,400. 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.
