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 814628576. Listed at 14 retailers as of November 5, 2026, with prices from £1,262 to £3,476, a £2,215 spread on the same certified stone. NZ Jewellers lists it at £3,476. 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.
