Does anyone else use gems?

The human body is truly capable of many things that most people seem to think isnt. a mother seeing her child trapped in the mouth of a shark pry's its jaw open and snaps it, saving the child and walking away without any serious injuries. if humans were to fully utilize all 100% of our muscular strength, we would cause our own bodies to fall apart from exertion. these are things that were and are proven by science, that the human body is a weapon that even itself has no full understanding of. i mean to this day scientists are trying to unravel still the many mysteries of the mind, how it works, what causes certain synapses to fire in certain ways, what makes certain brain cells link together to form new memories and abilities, and how the brain is able to perceive various things. even some scientists are trying to unravel the mystery of the human spirit, so to say that something like using gemstones for mystical purposes is pure bollocks, well, if its good enough for some smart alleks, then it ought to be fine enough for everyone.

i myself have never tried this, per say. sure using gemstones ive no experiences in, but other mediums yes. theres a knight piece from a chess set i own, wooden, and its the black knight, that ive used for various practices when relating to things like the aura, a persons own individual energies, and so on. some things just arent able to be explained. i mean, humans are the only animals on earth to have had a more massive affect on the planet than any other animal; ants may have carved into the crust, as well as other burrowers, but no animal has ever harnessed the energies of the foundations of life, and in turn through sheer human nature turned them into a weapon capable of destroying the planet many times over. so yeah, its entirely plausible that this gemstone stuff works. i mean, i can believe it. but, then again the conflict of science and rational experimented facts are oft times the counter to pseudo-scientifical advances. or so as far as i know.
