Christmas Minerals!

I got in my stocking a really cool clear Calcite crystal, and an amazing Bismuth crystal!  I have never seen or heard of these before, they are so awesome!  Here's a pic I got from amazingrust.com.  My sample looks just like this on the bottom.  On top it's like a cluster of pyramids that are beautifully colored.


















Isn't that cool!?  The outsides of the crystal grow faster than the insides, making it a hollow square spiral.  The metal oxidizes on the outside which is what gives it the coloring.  (Read more about it at http://amazingrust.com/experiments/how_to/Bismuth_Crystals.html).
