Serpentine is a lovely green translucent, waxy silicate of magnesium. it is often mistaken for various types of jade, and some stones called "jade" are actually types of serpentine. A major difference between the two semi precious stones is that serpentine is softer and less dense than most real jade. Its name comes from the word "serpent," or snake, perhaps because of its mottled green colors and patterns that can resemble snakeskin. Most of serpentine's history is tied in with the history of jade, as the two were (and are) often confused.
Metaphysically, serpentine is said to restore self-confidence, dispel fear and enhance meditation. It also is believed to balance female hormones and increase milk production in nursing mothers. Serpentine is found in the British Isles, China, South Africa and the U.S.A.
