The listing, Pentacle necklace has ended.
Pentacle necklace designed to look like five brooks put together to make a star with a leaf in the middle and a ring around it with swirls in it. Cord is adjustable, just slide the knots at the back. I don't know what metal it is, sorry, but I have one of similar make from the same place but a different pentacle design that I were every day and I'm allergic to nickel and haven't had a reaction, so this probably doesn't contain nickel, but don't quote me on that, I'm not 100% sure, each piece could be completely different.
