Phosphosiderite Orchid Coloured Gemstone
A wonderfully unique orchid coloured gemstone, phosphosiderite is a form of iron phosphate which comes primarily from Chile. Although used as a lapidary material, it's not seen that often because it's a relatively soft and brittle mineral which makes it quite difficult to work with.
Designed in a hand-made sterling silver setting, the colour of this gemstone is ideal for summer and is sure to attract plenty of attention. It has been very slightly reduced because there is a minor firescale mark on one side of this phosphosiderite pendant which can just about be seen in our second photo. Firescale marks resemble tea stains and are caused when certain metals are heated at very high temperatures. The mark is caused by an interaction between the silver and oxygen and is more difficult to avoid in jewellery that's worked entirely by hand. When polished the firescale mark is almost unnoticeable but as the silver tarnishes it becomes slightly more visible.
To minimise the build-up of tarnish on sterling silver jewellery simply keep it covered when not being worn and use a blue silver cloth occasionally to buff the silver. Chemical silver dips should never be used on jewellery that features a natural gemstone.
