Natural Phosphosiderite 4mm Faceted Bicone beads (15.5 inch strand)
These beads are rich purple and caramel color. Very beautiful.
Phosphosiderite can be found in small amounts at many localities including Germany, France, Portugal, Sweden, Liberia, South Africa, Mozambique, the United States including here in the Black Hills of South Dakota in the Bull Moose mine, Canada, Brazil, and Argentina. Phosphosiderite forms as “an alteration product of triphylite in zoned complex granite pegmatites” and can also be a soil constituent as well as a replacement mineral in bones and shells
