This 3.4ct lab-grown princess 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 LG811642759 or 811642759. Listed at 9 retailers as of October 29, 2026, with prices from $3,773 to $14,360, a $10,587 spread on the same certified stone. With Clarity lists it at $14,360. 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.
