Crystal

Rock crystal is usually clear like glass but can also be a little clouded.
Anyway you can see through it.

Magical Powers: 

People think I’m cold because they can see through me, but the opposite is true: I bring you patience, love and warmth and ensure that you never give up. I help you learn to look, feel and act according to your heart. Healing Powers:

A rock crystal may look cold but is quite the opposite. It will teach you to
see, feel and act from your heart. And that is not all. It  will bring you patience,
love, courage and warmth and helps you not to give up.

Someone with the zodiac sign Leo will respond very well to this stone.

 Crystal is the stone that gives power to all the other stones. Every piece of magical jewelry starts out as quartz. As soon as they fill up with magic they start to change color and finally turn into any stone you want. If the magic is spent, they will be colorless again. Quartz is best to be looked at as a magic battery. It will hold the spell of your choice. It works best if you know the magic of a gemstone through and through.

In the old days people believed rock crystal was frozen water that could not melt
and had to stay frozen for all times. ("Cristallos" is the Greek word for ice).
Once upon a time, long ago skulls made out of rock crystal were found in
Central-, and South-America! These were made by ancient peoples who believed
rock crystal was a very special stone.
Fortune-tellers used to look into a crystal ball to predict your future.
