About this 1.7ct natural princess diamond

This 1.7ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1448885927. Listed at 18 retailers as of November 2, 2026, with prices from £3,755 to £8,464, a £4,709 spread on the same certified stone. NZ Jewellers lists it at £8,464. 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.
