Listed at 10 retailers as of November 5, 2026, with prices from £4,256 to £8,652, a £4,395 spread on the same certified stone. NZ Jewellers lists it at £8,652. 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.
