Stones are widely used in jewellery making as they are so varied. Jasper is an
opaque stone and can come in many colours. Jasper beads are usually heavily
patterned due to the consolidation process in the original sediment. As jasper
beads are so varied they are sometimes named after the place they are found, or
their appearance. Some common types are Autumn Jasper, Picture Jasper and
Dalmation Jasper Stone.
