This 5.05ct lab-grown marquise sits in the over five carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG836626320 or 836626320. Listed at 9 retailers as of October 31, 2026, with prices from £1,262 to £4,538, a £3,276 spread on the same certified stone. Brilliant Earth lists it at £4,538. 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.
