About this 1.5ct natural princess diamond

This 1.5ct natural princess sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 729536854. Listed at 15 retailers as of October 27, 2026, with prices from £2,095 to £4,075, a £1,980 spread on the same certified stone. NZ Jewellers lists it at £4,075. 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.
