About this 3.91ct lab-grown cushion diamond

This 3.91ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG675529513 or 675529513. Listed at 3 retailers, with prices from $730 to $4,086 at Rare Carat, a $3,356 spread on the same certified stone. Cut grade matters more than carat or clarity for visible brilliance.
