This 3.05ct 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 LG831687428 or 831687428. Listed at 12 retailers as of October 30, 2026, with prices from €843 to €2,824, a €1,981 spread on the same certified stone. Brilliant Earth lists it at €2,824. 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.
