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 November 5, 2026, with prices from £1,548 to £2,732, a £1,184 spread on the same certified stone. Helzberg Diamonds lists it at £2,732. 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.
