About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG749513503 or 749513503. Listed at 11 retailers as of November 1, 2026, with prices from £189 to £837, a £648 spread on the same certified stone. MOH London lists it at £837. 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.
