This 0.51ct natural princess sits in the half to three-quarter carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 815624006. Listed at 9 retailers as of November 2, 2026, with prices from £313 to £1,332, a £1,019 spread on the same certified stone. NZ Jewellers lists it at £1,332. 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.
