Agate Tumble White Beads

Agate is a banded shell-like chalcedony, sometimes containing opal substances. The bands can be multi-coloured or of the same colour. German Agates have soft to strong colours (e.g. pink, red or brown) and are separated by bright gray bands. The South American Agates are a dull gray and without any special markings. 

This gemstone was originally found in the River Achates in Sicily, this is where its said to have got its name from. It can be found all over the world but dominantly in Africa, Asia, Brazil, Egypt, Germany, India, Italy, Mexico, Nepal and the United States of America.
