This 1.03ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GCAL 330950162. Listed at 9 retailers as of November 4, 2026, with prices from £173 to £714, a £541 spread on the same certified stone. MOH London lists it at £714. 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.
