Mexican Sterling Silver Snake Vintage bracelet. Both the head, and the tail of the snake have a dark brown flecked stone in them. The bracelet is marked 925 Mexico and has TM-M7. The bracelet is 2 5/8 inches inner diameter, and the head is 5/8 inches at the widest part. The tail is 3/8 of an inch. The silver on the bracelet is rounded, and I think hollow, though it is very thick and substantial. It stays put when worn pushed above the wrist.
