This 0.78ct lab-grown princess sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG774603770 or 774603770. Listed at 11 retailers as of October 29, 2026, with prices from €393 to €1,067, a €674 spread on the same certified stone. MOH London lists it at €1,067. 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.
