This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 683502555. Listed at 14 retailers as of November 4, 2026, with prices from £1,730 to £4,038, a £2,308 spread on the same certified stone. NZ Jewellers lists it at £4,038. 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.
