About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI 577372972. Listed at 16 retailers as of October 28, 2026, with prices from £4,672 to £9,091, a £4,419 spread on the same certified stone. NZ Jewellers lists it at £9,091. 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.
