This 0.31ct lab-grown marquise sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG544242229 or 544242229. Listed at 11 retailers as of November 2, 2026, with prices from $111 to $1,009, a $897 spread on the same certified stone. MOH London lists it at $1,009. 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.
