It's big and heavy, its uncomfortable because of the large size
I don't want to give a bad review but this pendant is bulky and I won't be wearing it because it's giving me a headache, not from the properties but from the size and weight of it.  I'm sitting and letting it rest on my shoulder and my headache has gone away.  I'm not really a jewelry wearer and would prefer something almost weightless.
