About this 2.57ct lab-grown marquise diamond

This 2.57ct 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 LG762544476 or 762544476. Listed at 15 retailers, with prices from $2,743 to $13,470 at Taylor and Hart, a $10,727 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.
