Listed at 8 retailers as of October 28, 2026, with prices from £173 to £601, a £428 spread on the same certified stone. MOH London lists it at £601. 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.
