Sacred stones are rocks that have significance.

A stone need not be a precious gem to be sacred. It could be a pebble that you had in your pocket when you're life was almost lost, or a piece of hematite your best friend gave to you in a handmade necklace.

Sacred stones can also be arrangements of stone.. Circular pseudo-chairs around a campfire by moonlight, stairways in a forbidden forrest, mounds of rock peacefully placed in a garden placed specifically because they're special, no tangible reason perhaps...

I'm not talking about New Age crystal healing.
Just the personal meaning of rocks. Simple rocks and their magic.

Colorado has oodles of sacred stones and mountains.
I left part of my soul with them when I visited and saw their power.

That is my definition of sacred stones.
