This is a question I am asked all the time. Does my crystal still work if it's broken? In short, my belief is YES. When you think about it, your crystal was broken when it came to you. The miners removed them from their natural habitat which technically means they were most likely broken in some way to begin with. With that being said, I do think it's important to give them a re-tuning if you dropped it or it broke in some way. Lost crystals is another question I'm asked frequently. Does it mean anything if you lose a crystal?
Here are a few videos that you may find helpful. I discuss various tips on what to do with a broken crystal as well as my personal beliefs on broken or lost crystals. Enjoy!
