I can completely relate to this, and I have a pretty interesting story behind it.
A few months ago I was having family troubles, so my husband invited some of his friends over to help us sort things out. One of his friends was a stone reader, and as he read my personality and troubles in the stones he pointed to the amethyst, that was positioned far away from the rest. The amethyst is the healing stone, he told me, and that my main problem was that I was being too defensive of my soul wound and lashing out at the people who really wanted to help me heal.
Now, I've been incredibly lost in my own personal pains for a long time.
I've also been obsessed with amethysts for just as long.
I didn't really understand why, but amethysts really appealed to me. I wanted to wear them, and hold them, and I named a character in one of my stories Amethyst. I realize now that I was trying to heal, and so I was pulling all of that healing energy toward me.
As of right now, I am more interested in leopard skin jasper. I like looking at them, because they look like they have little landscapes painted onto them. There's something mesmorizing and comforting about looking at those distant lands in the rocks.
