Chalcedony is actually a type of agate, which is a member of the quartz family of stones. Agates are believed to have been formed millions of years ago during volcanic eruptions. The volcanic lava flows left cavities filled with gas. As the flows cooled, these cavities allowed for mineral bearing solutions to enter and the combinations of these solutions along with heat, pressure and millions of years allowed the agate or chalcedony to form.
Chalcedony will come in several different colors including grey, blue, pink, green, orange, and purple. Chalcedony is said to strengthen the body and mind and when worn will give the wearer a sense of clarity so they may decide what they like and don't like. It is also said to help one emotionally, intellectually and be good for your self esteem.
