This is a wonderful stone for those who need grounding. Obsidian is a very protective stone, and is excellent for removing negativity. Origin: Mexico
Approximately 4″ x 7/16″ and 8.0 ounces (205.7 grams).
It is also excellent protection against psychic attacks. In particular obsidian protects the gentle from abuse, and is used to cut attachment cords to release one. It is a very grounding stone, and very healing. Obsidian is also an excellent manifestation stone. Physically it is said to benefit the stomach, intestines, muscle tissue, and can rid one of bacterial or viral infections. It sharpens and focuses internal and external vision, and helps get in touch with buried issues before they explode.
I have probably been seeing Black and Whites for around a year or so (2012). These crystals, no matter what they are, are important because the black and white are together. The two are all about the balance of things, the yin/yang. Black and Whites help us remember how important the balance of everything is. I keep hearing that this is the time of the Divine Feminine, and I know that is true, but I believe this, too, is all about balance.
