Listed at 24 retailers as of November 4, 2026, with prices from £4,256 to £8,513, a £4,256 spread on the same certified stone. NZ Jewellers lists it at £8,513. 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.
