About this 1.86ct lab-grown princess diamond

This 1.86ct 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 LG743512164 or 743512164. Listed at 12 retailers as of October 31, 2026, with prices from $3,339 to $15,211, a $11,872 spread on the same certified stone. With Clarity lists it at $15,211. 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.
