About this 1.7ct natural princess diamond

This 1.7ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI 492127439. Listed at 15 retailers as of October 30, 2026, with prices from £4,297 to £8,240, a £3,943 spread on the same certified stone. NZ Jewellers lists it at £8,240. 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.
