This 1.54ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754595659 or 754595659. Listed at 30 retailers as of November 2, 2026, with prices from $726 to $4,230, a $3,504 spread on the same certified stone. With Clarity lists it at $4,230. 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.
