Transformation's what you're after? Moldavite's the stone for you! Out of all the potential stones to use for transformative work, Moldavite is absolutely the premiere mineral. Moldavite breaks through obstacles like nothing else, and it will push you towards whatever you've set your intent on. Something particularly interesting about this stone is that people that need it, absolutely zero in on this stone. They will manage to pick up every piece of jewelry with Moldavite in it, even if it's surrounded by other stones. I rather suspect the Moldavite itself is calling to the person, loudly. ;)
Another interesting point about this stone is that some people love it more than a cat on catnip, and other people absolutely can't wear it. There actually is a minority middle ground of people that can wear Moldavite, as long as they also wear a grounding stone, but most of the time, it's one or the other. It's really quite fascinating to see where people fall on the spectrum with this stone, and in my experience, it's often directly correlated with whatever that person's currently working with or on in their life.
So where does this stone come from? Moldavite is actually a rare stone, found only in one place in the world, the Moldau River Valley in the Czech Republic. Moldavite is formed in asteroid impact where essentially, the meteorite hit, everything vaporized and the re-solidified, and voila, Moldavite was born. Of course, nobody really knows why Moldavite only formed in this one location. After all, there's been plenty of impacts throughout Earth's history, but to date, no matter how much people have searched, no other deposits of Moldavite have ever been found.
Okay, I know you're all saying, that's all great, but what does it DO? I'm so glad you asked ;)
Moldavite, as I mentioned before, is a powerfully transformative stone, but it also carries a melding of Earth and Heaven in the sense that the re-solidified material is likely some combination of Earth and Asteroid. It's both the 'otherwordly' and the home planet, and can create potent shifts in consciousness for that reason.
Moldavite is also an intensely protective stone when dealing with 'otherwordly' energies such as Spiritual Healing or Psychic Abilities. However, it should be noted that this stone is also extremely direct in its energy. It doesn't pull its punches and it WILL shove things hidden in the shadows out into the light, whether we want to see them or not.
This is not a stone for the faint hearted, or for those that are wired to respond better to a soft touch, but it is effective. My personal take is that it's sort of the New Yorker of the mineral kingdom in terms of how it speaks. It's results oriented and doesn't waste time. Need a fire lit under your bottom? Moldavite's your stone! lol
