About this 1.22ct natural princess diamond

This 1.22ct natural princess sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567590445. Listed at 5 retailers as of November 1, 2026, with prices from £1,774 to £2,212, a £438 spread on the same certified stone. Blue Nile lists it at £2,212. 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.
