This piece holds real quartz. The key is symbolic of the wisdom that is unlocked for you when you use this piece.  The quartz doesn't come from Earth, though.  The quartz that this piece is made up of comes from a place in Heaven called the Cave of Proverbs.  The Cave of Proverbs is an ever-growing cave upon which is written all the wisdom of God's knowledge, which is kind of what the Book of Proverbs in the Bible is.  So, I guess you could say that the Book of Proverbs doesn't end in the Bible.  It doesn't end at all, really.  Either way, this quartz comes from the Cave of Proverbs and you should be glad that it does because it holds all the wisdom that the cave has to offer.  This piece is to be used as a pendulum.  You will ask it yes or no questions and it will give you answers according to the divine wisdom that only God has to offer.  That is not it, though.  While you own this pendulum you will be able to develop a direct connection to the Angel of Fate.  This is a direct telepathic connection.  Through this connection, you will be able to relay to the Angel of Fate what it is you want to be played out in your life, according to your destiny, as it effects you.  This means that you can only use this piece to affect your destiny directly.  You can't use it, for instance, to destroy somebody else's destiny, affect the destiny of the world, etc.
