I think in Anthropology and Jewellery circles you will find the understanding is that Amulets magically protect or repel, Talismans are meant to attract, and they are both Charms.
I've found the word "Amulet" is more frequently used.
There is however a dealer with a showcase of general ethnic jewellery in Harvey Nicholls department store, Knightsbridge, London, called "Talisman Gallery". It sounds nice and exotic!
