This 1.5ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG841638502 or 841638502. Listed at 12 retailers as of November 2, 2026, with prices from $243 to $1,520, a $1,277 spread on the same certified stone. Brilliant Earth lists it at $1,520. 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.
