This 5.09ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG626460772 or 626460772. Listed at 14 retailers as of October 31, 2026, with prices from £1,349 to £4,290, a £2,941 spread on the same certified stone. Taylor and Hart lists it at £4,290. 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.
