All gemstones have one thing in common....they originate from the hot magma, of which the inside of the earth is composed.
From the very infancy of the human race, gemstones have exercised a powerful fascination.  The therapeutic use of gems is not a new or alternative healing method. The art of healing with stones is thousands of years old. Much evidence exists, including the first Chinese medical book, written 5000 years ago, which has detailed descriptions of gemstones and their influence on the human body.  There are also numerous references made to gemstones in the Bible. Crystals are exceptional transmitters and receivers of energy.  They are used in modern medical practices today.  They are compressed to produce electricity and sometimes light.  This property is harnessed in ultrasound machines to produce sound waves.
Crystals work through resonance and vibration, rebalancing the biomagnetic field that surrounds and interpenetrates the physical body.  They work on the physical, emotional, mental and spiritual levels of being.  They realign subtle energies and dissolve issues, getting to the root cause.  Crystals work on the cause rather than merely alleviating the symptoms. 
Neither time nor faith in the power of crystals are factors in the effectiveness of healing stones. It doesn't matter whether or not you believe in their power....the stones will have an influence on the body. Those who are more sensitive will experience their effects more quickly and intensely.
Each bracelet has been dedicated, with focused energy to it's global purpose. However, when you receive your bracelet, please clean it under running water to clear any negative energy; then, holding your bracelet out in front of you, state your specific purpose and intent.
