This 3.51ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG850679708 or 850679708. Listed at 6 retailers as of October 28, 2026, with prices from £566 to £2,124, a £1,557 spread on the same certified stone. Rare Carat lists it at £2,124. 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.
