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 LG845656920 or 845656920. Listed at 13 retailers as of October 30, 2026, with prices from $1,038 to $4,225, a $3,186 spread on the same certified stone. MOH London lists it at $4,225. 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.
