This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG842656912 or 842656912. Listed at 2 retailers as of October 30, 2026, with prices from £129 to £200, a £71 spread on the same certified stone. Loose Grown Diamond lists it at £200. 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.
