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 LG825687856 or 825687856. Listed at 18 retailers as of November 3, 2026, with prices from $584 to $4,519, a $3,934 spread on the same certified stone. Brilliant Earth lists it at $4,519. 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.
