About this 1.56ct lab-grown marquise diamond

This 1.56ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG553237656 or 553237656. Listed at 26 retailers, with prices from $398 to $2,244 at With Clarity, a $1,846 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.
