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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2487569658. Listed at 14 retailers as of November 5, 2026, with prices from £1,663 to £4,249, a £2,586 spread on the same certified stone. NZ Jewellers lists it at £4,249. 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.
