The Atlanteans used crystals quite extensively, and misused them to such a degree that they eventually contributed to the catastrophe which caused the downfall of Atlantis.

The Atlanteans used the knowledge of the crystal refraction, amplification and storage.

It is known that a beam of light directed intensely and focused specifically on certain series of facets in a gem will, when it exits from the reflective plane of the gem, be amplified rather than diminished.

These amplified energies were broken down into a wide and sophisticated spectrum of color and sound frequencies.

The Atlanteans used the spectrum of this energy for a specific purpose, much as one would use petroleum in terms of its various spectrum limitations for specific purposes.

Today many of these crystals are being found --often by those who worked with them in the time of Atlantis.
