About this 1.59ct lab-grown marquise diamond

This 1.59ct 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 standard cut grade and certified by IGI LG754594529 or 754594529. Listed at 25 retailers, with prices from $759 to $4,770 at Brilliant Earth, a $4,011 spread on the same certified stone. 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.
