About this 1.58ct lab-grown marquise diamond

This 1.58ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG825663662 or 825663662. Listed at 16 retailers, with prices from $445 to $2,261 at Brilliance, a $1,816 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.
