This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 647430678. Listed at 15 retailers as of November 5, 2026, with prices from £4,718 to £9,047, a £4,329 spread on the same certified stone. NZ Jewellers lists it at £9,047. 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.
