This 1.57ct lab-grown princess sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG723518996 or 723518996. Listed at 12 retailers as of October 29, 2026, with prices from $1,722 to $6,410, a $4,689 spread on the same certified stone. Brilliant Earth lists it at $6,410. 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.
