I've notice on ebay, in the metaphysical area, that a lot of people are selling jewelry claiming to have a Djinn bound to it.  My question is, has anyone experienced such an entity.  If so, what was involved in the summoning? Do you actually see the Djinn? Do they grant wishes?

Well goodness, I thought I had heard most things, this one is new for me. I'm curious what responses you will get.

I have never heard of a Djinn before.  If you type in Summoning Djinn into google you will find some information.

I Dream of Jeannie,
Aladdin.
Rub the lamp and out comes the Magical Djinn.

Ok lol I believe that there are djinn type beings out there, but not really to the extent of the old tales of aladdins genie and such.  I also very much doubt that it is as easy to find one as ebay haha  

With all magics one must be careful.  We here genie and such and think "Yes, 3 wishes!"  But you must be careful what you wish for.  They can interpret it any way that they please, asking for a million dollars may find you have robbed a bank to get it.  I can't help but think of the movie wishmaster, there are evil entities out there who feed off of our desires, so be careful if you do decide to try this out and find something really is attached to it.
