About this 1.21ct natural princess diamond

This 1.21ct 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 2536165432. Listed at 24 retailers as of October 30, 2026, with prices from £2,453 to £5,559, a £3,105 spread on the same certified stone. NZ Jewellers lists it at £5,559. 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.
