This 4.51ct lab-grown princess sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG768602635 or 768602635. Listed at 10 retailers as of October 30, 2026, with prices from €1,090 to €5,073, a €3,983 spread on the same certified stone. Brilliant Earth lists it at €5,073. 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.
