This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG778633012 or 778633012. Listed at 27 retailers as of November 3, 2026, with prices from $300 to $1,580, a $1,280 spread on the same certified stone. Brilliant Earth lists it at $1,580. 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.
