Listed at 9 retailers as of November 5, 2026, with prices from £1,427 to £4,715, a £3,288 spread on the same certified stone. MOH London lists it at £4,715. 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.
