This 3.71ct 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 LG821641069 or 821641069. Listed at 9 retailers as of October 31, 2026, with prices from $3,594 to $13,500, a $9,906 spread on the same certified stone. With Clarity lists it at $13,500. 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.
