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 13 retailers as of October 29, 2026, with prices from $549 to $3,170, a $2,621 spread on the same certified stone. Brilliant Earth lists it at $3,170. 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.
