The reasons crystals are such a useful tool in energy work is because they vibrate. Not only vibrate they can amplify or “mimic” any vibration conducted through them. The mechanical pressure referred to earlier is actually present already in the most common crystal formation. The structure of a quartz crystal was created under pressure. The silicates and minerals contained with in the crystal are pressurized, that’s why crystals are known to shatter when large energies are passed through them or even when left in the heat or the cold. 

When we use a crystal we alter its vibration. As an energy worker, we are aware that simple thoughts have vibrations let alone when we focus our will, summon our energy and pass it through the stone. When this occurs we are easily able to create a huge beacon or battery, a continuous vibration of our will or intent. 

It then also becomes clear why different properties are attributed to different stones. Not only do we have different materials vibrating at different frequencies we also have coloured energies. Again we know that colour has a vibration of its own. 
 
When we interact with the vibration our aura experiences the vibration and we are comforted. I have also found that auras can be a little like tuning forks they will pick up a vibration from their surroundings and if we wish “mimic” it. Energy is magnetic. As soon as we adopt a vibration we attract similarly vibrating energies.

This principle holds true to healing with crystals too and any other application one can think of. It’s a simple case of energy magnetism and complementary vibrations.
So that is the basic theory or should I say my basic theory on crystal healings and working.

Before I begin to sound too scientific, I must say, I personally believe there is something mystic about minerals. I feel they are a gift from the earth and have power and wisdoms inside them. My explanation that it’s all subtle little electric pulse really doesn’t begin to explain why a piece of kyanite relieves stress or why black tourmaline is can absorb negative energies.  

There are several methods for working with crystals
 
Attuning with Crystals and Stones
Programming a Crystal
Projecting Energy via a Crystal or Stone
Receiving Energy via a Crystal or Stone

Within these 4 methods/concepts I find a base for anything I could conceivably wish to do or achieve with a crystal. According to crystal researcher Marcel Vogel, a senior scientist with IBM for 27 years.

NOTE:
Please be aware that Crystal Healing does not take the place of conventional medicine, nor does it replace the advice of a qualified medical practitioner. Always consult a GP for an acute or infectious condition, and problems of an urgent nature. Continue with your prescribed medication. Healing is a complementary therapy that works effectively alongside orthodox/conventional healthcare, thus expanding your treatment options.
