This 3.03ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG825655562 or 825655562. Listed at 10 retailers as of October 28, 2026, with prices from $445 to $2,640, a $2,195 spread on the same certified stone. Rare Carat lists it at $2,640. 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.
