Black Onyx and Sterling Silver Studded Earrings

Made of sterling silver and black onyx. Another set from Kathmandu. The dime is for size reference. I love the look of them, and the black onyx stone is for inner strength, which is one reason why i love this stone. But I like smaller stud earrings. I don't see a stamp, but that's not an uncommon thing with handmade pieces like this from some of the more obscure parts of the world where he gets these from. These do have a bit of heft to them...especially considering the size of them.
