About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2534155557. Listed at 8 retailers as of November 5, 2026, with prices from £1,718 to £4,011, a £2,293 spread on the same certified stone. NZ Jewellers lists it at £4,011. 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.
