And here's a link to the main shop:
The Hamsa, or Hand of Fatima, is a protective symbol throughout the Middle East, and it's worn to protect against the evil eye. It can be hung with the fingers up or down (though this earring pattern obviously features the fingers down.) Here's a bit more about the symbol from Wikipedia. And here's a link to my favorite "what's that amulet?" site, The Lucky W Amulet Archive.
P.S. I have gold and silver pairs in my Etsy jewelry shop for those who'd rather purchase the finished earrings.
