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 standard cut grade and certified by IGI LG836608706 or 836608706. Listed at 10 retailers as of October 29, 2026, with prices from $1,529 to $5,638, a $4,109 spread on the same certified stone. Brilliant Earth lists it at $5,638. 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.
