With a colour similar to that of the stunning purple Thai Orchid, Phosphosiderite’s name is derived from its make up of phosphorous and iron oxide.
Until recently, as this gem is very soft, it has not been set in jewellery. However by stabilising it through the use of treatment, its hardness can be increased making it more durable. As the gem’s wonderful opaque purple lustre makes a perfect companion to Amethyst, the designers at Annabella are currently experimenting with setting Cabochon cut stabilised Phosphosiderite alongside Amethyst in a collection of earrings and pendants.
Phosphosiderite can be found in Cornwall England, Columbia, Chile, Canada, Brazil and several other mining locations around the world.
