This 1.53ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG519238358 or 519238358. Listed at 6 retailers as of October 29, 2026, with prices from $691 to $2,840, a $2,149 spread on the same certified stone. MOH London lists it at $2,840. 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.
