About this 0.82ct lab-grown marquise diamond

This 0.82ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG722561857 or 722561857. Listed at 2 retailers as of October 27, 2026, with prices from $245 to $880, a $635 spread on the same certified stone. Brilliant Earth lists it at $880. 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.
