This 3.15ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG695505158 or 695505158. Listed at 3 retailers as of October 31, 2026, with prices from €4,376 to €10,159, a €5,783 spread on the same certified stone. Brilliant Earth lists it at €10,159. 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.
