This 5.02ct 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 LG840643731 or 840643731. Listed at 7 retailers as of October 28, 2026, with prices from £1,416 to £4,534, a £3,119 spread on the same certified stone. Rare Carat lists it at £4,534. 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.
