This 1.6ct 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) and certified by IGI LG778646311 or 778646311. Listed at 24 retailers as of November 2, 2026, with prices from $544 to $3,021, a $2,478 spread on the same certified stone. Brilliant Earth lists it at $3,021. 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.
