About this 1.1ct lab-grown cushion diamond

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 November 3, 2026, with prices from £301 to £1,304, a £1,003 spread on the same certified stone. MOH London lists it at £1,304. 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.
