This 1.53ct 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 LG496118680 or 496118680. Listed at 6 retailers as of November 5, 2026, with prices from $848 to $3,557, a $2,709 spread on the same certified stone. MOH London lists it at $3,557. 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.
