This 1.51ct 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 LG825655953 or 825655953. Listed at 23 retailers as of October 31, 2026, with prices from $1,012 to $4,684, a $3,671 spread on the same certified stone. Brilliant Earth lists it at $4,684. 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.
