About this 2.91ct lab-grown marquise diamond

This 2.91ct 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 LG762545069 or 762545069. Listed at 12 retailers, with prices from $3,048 to $15,259 at Taylor and Hart, a $12,211 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.
