Natural Handmade Blue Chalcedony Pendant.

Blue chalcedony is the birthstone for May and is associated with the throat and speaking. It is also a zodiac stone for Geminis, who are born between May 21 and June 20. Blue chalcedony is also known as "The Speaker's Stone" because it is thought to improve communication and ease self-doubt. Some believe it can be a good luck charm for actors and public speakers.
