Unfortunately they are not silver or gold- just trinkets sold on the streets! No doubt you can find genuine ones from gold shops etc as well. They are all wall hangings, some keyrings at the bottom. The message is usually a blessing for the house, and they are popular presents- when my Israeli friend heard that I'd moved, she sent me one that would ward off bad luck from the house.
Just a question - are these earrings /pendants or wall hangings? They are beautiful and I presume made out of silver or gold. Can you clarify?
