What do the letters OTC mean on a 925 Italian silver necklace？-Well, geez, usually when you see the letters OTC on a 925 Italian silver necklace, it doesn't have a standard or widely recognized meaning specific to jewelry. It could potentially be some kind of personal marking or a code that's unique to the maker or owner. Maybe it's a reference to something special or a symbol that has a particular significance within a certain context or group. But in general jewelry terms, OTC isn't a common abbreviation that has a well-defined meaning. How strange, huh?
