This 4.13ct lab-grown princess sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818640339 or 818640339. Listed at 21 retailers as of October 29, 2026, with prices from £4,888 to £22,332, a £17,444 spread on the same certified stone. With Clarity lists it at £22,332. 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.
