Yes, I heard something similar about it too, my grandmother told me that when I was little. Saturn sits. She also told me to be very careful with mirrors that do not show a fingerprint after being touched. LOL

It is also logical, because the crystal/stone stores data, in whatever form it is. I would never wear jewelry that has not been energetically cleansed. With the help of crystals, one can track and detect anything across time and space, because time is just an illusion just like matter. That is, unless they are soulless entities that are subject to time, even if time runs a bit slower for them than we know it.
