About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 816642229. Listed at 21 retailers as of November 2, 2026, with prices from £2,529 to £5,816, a £3,287 spread on the same certified stone. NZ Jewellers lists it at £5,816. 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.
