Listed at 23 retailers as of October 26, 2026, with prices from £258 to £1,252, a £994 spread on the same certified stone. MOH London lists it at £1,252. 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.
