Cell phone charm with amethyst, smoky quartz, black tourmaline and sterling silver
I made this cell phone charm with black tourmaline, amethyst and smoky quartz because they all protect us from negative energies of a cell phone. More about these gemstones:

Black Tourmaline purifies negative energy and changes it into usable energy. This crystal protects against cellphones, electromagnetic waves, radiation, psychic attack and all kinds of negative energies.  It is especially useful for the people with high levels of stress in their lives. Black Tourmaline helps to get rid of negative emotions, like anger and jealousy. Black tourmaline strenghtens the immune system, purifies the body of toxins and wastes, and helps to relieve pain.

Smoky quartz is one of the premier grounding stones, it helps to bring people back to earth. The darker the crystal, the bigger grounding qualities it has. This crystal helps to neutralize all the negative energies. That’s why it is suggested to use smoky quartz with bad mood and also with depression. Smoky quartz also blocks negative energies that come from computers and cell phones. In addition, it is recommended for people who need to concentrate on a specific activity like filling out a tax declaration, for students preparing for a test, etc. Since smoky quartz is often naturally irradiated, it is excellent for treating radiation-related illnesses or effects of chemotherapy.  It is also a great crystal to use when sunburnt. Smoky quartz helps to relieve pain, it helps with headaches and is also helpful for ailments of the abdomen, hips and legs.

Amethyst is a stone of spiritual protection, purification and transformation. It is used to get rid of bad habits since it has cleansing effect and it helps one find balance and restraint. Bad habits in question include alcoholism, smoking, drugs, bulimia, etc. Amethyst also aids travellers and therefore it is good to keep it in the car where it helps on reach the destination safely. Amethyst eliminates fear of changes and eases one's view on the future. It is especially useful for children, who often express their emotions with anger and rage, because of its calming and balancing effect. It also relieves sadness and grief, and helps to cope with losses. Due to its cleansing effect, it is used to block geopathic stress. Amethyst relieves pain, headaches, reduces swellings and injuries. It is beneficial for lungs, respiratory tract, skin and digestive tract.
