This 0.31ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG717511523 or 717511523. Listed at 16 retailers as of October 26, 2026, with prices from $200 to $2,080, a $1,879 spread on the same certified stone. MOH London lists it at $2,080. 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.
