This 1.6ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG846654915 or 846654915. Listed at 23 retailers as of October 28, 2026, with prices from $659 to $3,538, a $2,879 spread on the same certified stone. Rare Carat lists it at $3,538. 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.
