Agate, General Description
- Geological - A variety of Chalcedony formed from layers of quartz. Various colors and shades. When it is concentrically banded (often wild patterns) it is called by the subvariety name Agate. When it is in flat layers/bands it is called by the subvariety name Onyx. (Note: Many non-banded forms of chalcedony - i.e. Moss agate - are often erroneously called 'agates'. True agate is concentrically banded. Mottled and included chalcedonies are more properly called simply 'chalcedony'. Agatized wood is the name given to fossil wood where the replacement of the wood is by chalcedony, but the banding in this case is due to the wood structure, and the material is chalcedony, not true agate.) Often tiny quartz crystals form within the stone and add to the beauty and uniqueness of individual stones. These crystals are called drusy. Hardness of 6.5-7.
- Origin - All over the world including: the Africa, Asia, Brazil, Egypt, Germany, India, Italy, Mexico, Nepal, China, and the USA.
- Mystic Lore - Regarded as a stabilizing and strengthening influence. Composure and maturity. Good for eyes, stomach, intestines, blood vessels and skin.
