About this 1.03ct lab-grown cushion diamond

This 1.03ct 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 LG668410053 or 668410053. Listed at 11 retailers as of November 4, 2026, with prices from $225 to $1,177, a $952 spread on the same certified stone. MOH London lists it at $1,177. 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.
