About this 1.2ct natural princess diamond

This 1.2ct 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 2527891660. Listed at 14 retailers as of November 4, 2026, with prices from £2,185 to £4,792, a £2,607 spread on the same certified stone. NZ Jewellers lists it at £4,792. 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.
