This 1.5ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830619923 or 830619923. Listed at 15 retailers as of November 5, 2026, with prices from $747 to $3,156, a $2,408 spread on the same certified stone. With Clarity lists it at $3,156. 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.
