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 32 retailers as of November 4, 2026, with prices from $835 to $4,840, a $4,004 spread on the same certified stone. With Clarity lists it at $4,840. 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.
