This 3.01ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG818682278 or 818682278. Listed at 21 retailers as of November 3, 2026, with prices from $540 to $3,615, a $3,074 spread on the same certified stone. Brilliant Earth lists it at $3,615. 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.
