Not really, you could make a charm out of something that isn't breakable if you use the right conditions for it function (say a spell that senses an effect and then goes off). This is basically implied on p. 9 of
Pyramid #3/66: The Laws of Magic in the Charms R Us box.

Yes. The person wearing it would be the subject of the spell and it wouldn't take effect until it was worn.

Yes. In the past I've used the rules for Magical Patina (
GURPS Thaumatology, p. 88), but treated years as times its been used for a magical spell as a charm, e.g., 10 times of casting a spell on a particular bracelet gives a +1 to casting rolls to do it again.

Nope. It's implicit that you can use non-breakable charms, but you have to be smarter for the conditions of the spell going off so breakable charms are just easier.
