This 0.78ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825656603 or 825656603. Listed at 18 retailers as of October 30, 2026, with prices from €457 to €1,864, a €1,407 spread on the same certified stone. MOH London lists it at €1,864. 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.
