This 5.03ct lab-grown marquise sits in the over five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG845650665 or 845650665. Listed at 8 retailers as of October 28, 2026, with prices from £1,222 to £4,060, a £2,838 spread on the same certified stone. Rare Carat lists it at £4,060. 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.
