Up for your consideration is a Vintage Native American Sterling Silver Double Row Spiny Oyster Bangle Bracelet. This is pretty heavy, Stamped Sterling and has the Makers Mark of L.B. This is probably one of the heartier bangles I've come across in my many years of collecting Native Artifacts and Jewelry. I've taken pictures of each side as well as the stamping of Sterling and Makers Mark. It measures 2/3/4" in diameter and is 1/2" High making it pretty hefty and will make a great statement bangle. I purchased this from my travels to the Southwest from one of the tribes, not sure which one, sorry. It shows no deviations or wear except for the Patina which will remain. Please ask any questions, I'm more than happy to help!
