Listed at 14 retailers as of November 4, 2026, with prices from £1,711 to £3,996, a £2,285 spread on the same certified stone. NZ Jewellers lists it at £3,996. 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.
