This 0.31ct lab-grown marquise sits in the sub-half-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG537225545 or 537225545. Listed at 15 retailers as of October 26, 2026, with prices from $87 to $790, a $703 spread on the same certified stone. MOH London lists it at $790. 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.
