This 1.1ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG811672194 or 811672194. Listed at 10 retailers as of October 29, 2026, with prices from $272 to $947, a $675 spread on the same certified stone. MOH London lists it at $947. 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.
