I too was skeptical about amethyst, but thought if I could pick one up on ebay for under 2 bucks, what could it hurt? I have an enameled bowl, probably over metal, I put it in. I won a cheap bid for a nice smooth round beaded necklace, and put the whole strand (it is just string, I believe...Will have to restring someday I imagine), My cat had a real flea problem and It was no longer in my budget to keep using Revolution, Which was working, but hated the poison factor and was amazed this really seemed to work for us. only used it for 6 months now, but it was sure worth the gamble for $2, I am shocked. (and we are happy!)
