Vintage Chinese Export Sterling Ball Pendant Turquoise Stone

Here for your consideration is a nice vintage sterling ball pendant. Based on the construction I think this is an old Chinese export piece. It is not marked but test for sterling.It is about 1.25" tall and weighs about 6.9 grams. This has a patina and left unpolished. The stone looks like turquoise. There is one very tiny little dent. It is overall in good wearable vintage condition.
