About this 0.5ct lab-grown marquise diamond

This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG836610277 or 836610277. Listed at 10 retailers as of November 1, 2026, with prices from $592 to $1,636, a $1,045 spread on the same certified stone. MOH London lists it at $1,636. 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.
