Listed at 16 retailers as of November 2, 2026, with prices from £113 to £655, a £542 spread on the same certified stone. MOH London lists it at £655. 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.
