About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded G 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 1555013930. Listed at 11 retailers as of November 5, 2026, with prices from £1,819 to £4,687, a £2,867 spread on the same certified stone. NZ Jewellers lists it at £4,687. 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.
