This 0.7ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG628455571 or 628455571. Listed at 13 retailers as of November 5, 2026, with prices from £90 to £1,027, a £937 spread on the same certified stone. MOH London lists it at £1,027. 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.
