Dark Moon Magic author Cerridwen Greenleaf has written a new blog post on the power the gemstones hold.

Where do gemstones get their power? They all have a crystalline structure that can collect, store, and release electromagnetic energy, similar to the way today’s commonplace battery does.
Scientists and engineers have discovered through experimentation that a crystal will accumulate and concentrate the energy of any given energy field in close proximity. Further, they’ve discovered that if a crystal is squeezed, energy from within the crystal is released. Light can also be released during the compression of a crystal. While the expansion is infinitesimal, electrons are emitted and are then reabsorbed by the crystal, thus producing energy. Schoolchildren discover this by rubbing or heating crystals and feeling a marked static change. This is known as the piezoelectric effect. Anyone who doubts the power of this effect need only be told that it is one of the causes of earthquakes.
Quartz is the crystal most often used today in both scientific and spiritual realms. It is, perhaps, the most prevalent of all gemstones and can be found on every land mass on Earth. Common quartz was used in the world’s first radio broadcasts and enabled the chips that propelled the computer revolution. It stands to reason that quartz was the first crystal to be synthesized by manufacture. Today, man-made crystals are in vast usage in our watches, computers, and other electronic devices.
Quartz is composed of silicon and oxygen, the same basic minerals that make up this planet. Silicon dioxide (SO2), the building block responsible for the geologic makeup of the earth, is also inside us, which may explain why there is a natural attraction between our bodies and crystals.
