About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565521781. Listed at 13 retailers as of October 29, 2026, with prices from $2,950 to $5,567, a $2,617 spread on the same certified stone. Helzberg Diamonds lists it at $5,567. 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.
