About this 2.56ct lab-grown marquise diamond

This 2.56ct lab-grown marquise sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG744515120 or 744515120. Listed at 4 retailers, with prices from $6,450 to $12,384 at Novita Diamonds, a $5,934 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.
