Thanks very much for all the nice C&C's on
the geode entry.
Continuing with my rocks, here's a macro of
some Fool's Gold, (Iron Pyrites).
Metallic, cubic crystals, often striated.
Used during the 16th and 17th centuries for ignition in guns,
these days, it is used commercially in the production of paper,
sulphuric acid and photovoltaic solar panels.
It is used in some jewellery, but can't be fashioned into
fine items such as chains.
Quite pleased at the detail my little camera achieved.
