silver jewerly can kill you, dont drink this crap. get real silver, and dont settle for anything less than .9999 pure. I worry about my health and use not .9999 pure but .99999 (5) pure. thats the highest in the world you can get. its your body take care of it. some silver you buy out there has lead and cadium in it with traces of mercury, be very careful. only use .9999 canadian maple leaf coins are the best.
