This 8.56ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG735516632 or 735516632. Listed at 18 retailers as of November 1, 2026, with prices from £1,101 to £4,222, a £3,121 spread on the same certified stone. Rare Carat lists it at £4,222. 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.
