This 0.79ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG749565440 or 749565440. Listed at 4 retailers as of October 29, 2026, with prices from £302 to £820, a £518 spread on the same certified stone. MOH London lists it at £820. 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.
