Agate, a form of Chalcedony, comes in a variety of colours and designs almost as vast as its beauty. It forms by slowly filling a host rock, producing concentric bands over time. Agate often grows in nodule-shaped deposits which can be carved into a bowl. Agate bowls were collected by European royalty during the Renaissance. Historically, Agate was valued as a talisman and used to quench thirst and heal fevers. Legend states that Persian magicians used Agate to divert storms. Agate is thought to balance yin and yang, offer courage, protection and healing. It is also said to enhance creativity and intellect, stimulating one’s concentration, precision and analytic capabilities.
