This 0.34ct lab-grown marquise sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG544252228 or 544252228. Listed at 12 retailers as of November 1, 2026, with prices from £69 to £627, a £558 spread on the same certified stone. MOH London lists it at £627. 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.
