This 5.05ct lab-grown marquise 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 LG852630294 or 852630294. Listed at 5 retailers as of October 31, 2026, with prices from £1,429 to £4,019, a £2,590 spread on the same certified stone. Taylor and Hart lists it at £4,019. 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.
