Listed at 22 retailers as of November 1, 2026, with prices from £868 to £4,821, a £3,953 spread on the same certified stone. Brilliant Earth lists it at £4,821. 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.
