This 0.79ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG659416363 or 659416363. Listed at 4 retailers as of November 2, 2026, with prices from £444 to £594, a £151 spread on the same certified stone. Zales lists it at £594. 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.
