Stones with distinctive colours or patterns have been used as amulets since the dawn of time. Their colour or pattern often determined their use. Red or green stones, like coral or malachite, were thought to promote health and well-being. Serpentine was worn to protect against snake bites. The delicate patterns of fossilised coral or sea urchins were a powerful protection against witches and the evil eye.

All the stones in these three amulets are native to the south German alpine region. In the 18th century the inhabitants made amulets on an industrial scale for distribution throughout southern Germany.

These were bought for 6s 9d (for the three) at the International Exhibition, London, 1872
