My husband has a quartz crystal that was clear when he first started wearing it on a leather thong around his neck. Just recently it has started turning dark. It appears to keep getting darker and darker, and is a dark smokey now and looking like it is going to turn black.
I have not cleansed it for a long time. Could this be what is causing this?
If so, what would be the best way to cleans it? I've been told to bury it in the earth with sea salt, or to leave it in direct sunshine, or to put it inside a paper pyramyd. But no one has told me how long I should do any of these things.
I'm not real familiar with crystals except how to energize them, so any and all help will be appreciated.
