This 1.03ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840611849 or 840611849. Listed at 12 retailers as of November 5, 2026, with prices from $179 to $1,668, a $1,489 spread on the same certified stone. MOH London lists it at $1,668. 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.
