This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG700516097 or 700516097. Listed at 8 retailers as of October 28, 2026, with prices from $362 to $1,623, a $1,260 spread on the same certified stone. MOH London lists it at $1,623. 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.
