It probably means that some of the silver, the surface really, has picked up some oxygen. rusted as it s commonly known.

It could mean that the silver picked up any negative charged ion, the process of oxidation is not only applicable to oxygen.

Any high school book chemistry text will explain oxidation reduction reactions clearly enough to make sense of any book involving charms.

Oxidized silver is black (that's what tarnish is). What it most likely means is that the charms have intentionally been oxidized to provide a specific appearance, perhaps to emphasize a design more effectively.

Pure silver does not oxidize under normal conditions; it will, however, react with sulfur compounds and obtain a 'tarnish' after a time. On the other hand, since sterling silver is 92.5% silver (not pure), and typically alloyed with copper, the copper will oxidize under normal conditions, which results in quicker discoloration of the metal.

silver oxidized is a method of passivating silver, for a specific desired effect and shading, and protecting the silver from, any further undesired oxidization, in any unwanted effect. thus maintaining the origional artistic effect intended. thus you are making it tarnish, in a specific designed pattern.

silver which has been in contact with oxygen.

well,in my school experiment, we heat up potassium manganate (VII) to release oxygen together with the silver in the same test tube but they're not mixed together.

so when oxygen is released. it combines with silver therefore becoming silver oxide.
