About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG805605770 or 805605770. Listed at 9 retailers as of November 2, 2026, with prices from £166 to £1,019, a £853 spread on the same certified stone. MOH London lists it at £1,019. 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.
