This 1.1ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG566398192 or 566398192. Listed at 8 retailers as of October 29, 2026, with prices from $403 to $1,754, a $1,351 spread on the same certified stone. MOH London lists it at $1,754. 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.
