About this 1.09ct lab-grown princess diamond

This 1.09ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG602397170 or 602397170. Listed at 20 retailers as of October 29, 2026, with prices from $319 to $2,975, a $2,656 spread on the same certified stone. Brilliant Earth lists it at $2,975. 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.
