About this 1.06ct natural princess diamond

This 1.06ct 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. Listed at 3 retailers as of October 30, 2026, with prices from £2,928 to £3,700, a £772 spread on the same certified stone. Blue Nile lists it at £3,700. 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.
