About this 1.04ct natural princess diamond

This 1.04ct natural princess sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1568321966. Listed at 5 retailers as of November 4, 2026, with prices from £1,393 to £1,748, a £354 spread on the same certified stone. Blue Nile lists it at £1,748. 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.
