This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845658670 or 845658670. Listed at 14 retailers as of November 1, 2026, with prices from €201 to €1,073, a €872 spread on the same certified stone. Reve Diamonds lists it at €1,073. 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.
