Yes to the really nice ones, I have channelled some very pleasant Et's, using the crystal Moldavite.

About 20 million years ago a meteorite shower fell in the Moldau Valley of Czechoslovakia. The result of this shower was moldavite, a rare crystal of a bottle-green, translucent hue. Although some people believe that it is a true meteorite (formed in outer space), it is more generally believed that it originates from rock that was struck by a meteorite and melted. According to the latter belief, moldavite combines extraterrestrial and terrestrial properties.

It is generally considered to be one of the stones very important for this particular phase of human evolution. Many people feel that at this time there are countless souls who are not originally from Planet Earth, but from the Pleiades, Sirius, Orion, and other systems.

The belief fueling this thought is that for our Earth to fully heal itself, new races of beings are needed, those with what might be described as a more cosmic view of existence. These souls, incarnating for the first time on this planet, (and in some cases for the first time in a physical body) need a way to be grounded in the unique energies of this planet, and moldavite is one of the helpers for this.

At one time in my life, I would have dismissed this as a fascinating theory. I have since learned that ideas which I used to dismiss without a second thought have become part of my belief system.

You don't have to believe this theory, however, to benefit from moldavite, for we can more generally look at it as a stone that can both help us be comfortable in physical existence and remind us that our Earth is part of a much larger system of consciousness.

When placed on the third eye, moldavite helps us to establish the cosmic connection. When placed on the heart it teaches us to appreciate the gift of being here on Earth.

On a more practical level, many people have reported that moldavite helps to release all that is no longer needed for personal growth: old ideas: leftover emotional/mental habits, whatever you know on a deep level needs to go.

Because its energies are so powerful it's a good idea to keep it near you a lot when you first get one and to meditate with it regularly. Whenever moldavite is used in meditation it is recommended that a grounding stone: black tourmaline, hematite, tiger's eye, smoky quartz, red jasper, or obsidian, be placed by the feet for grounding purposes.

Special warning: You will find in time that more and more things seem to be unnecessary: the relationship you're hanging on to because it's comfortable and you don't like to be lonely, for example. You may find it more and more important to be honest with both yourself and others.

So even if you don't believe in extraterrestrial beings, moldavite is a valuable stone for you, but if you're just a bit curious, moldavite may open some doors. What these doors open to, well, you'll have to decide that.
