This 1.53ct 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 LG739511134 or 739511134. Listed at 2 retailers as of November 1, 2026, with prices from $3,104 to $4,169, a $1,065 spread on the same certified stone. Brilliant Earth lists it at $4,169. 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.
