This pendant is the rune ōs of the fuþorc (anglo-saxon) rune alphabet. Literally it means "god" and it symbolizes the creative power of word in all its forms, like poetry, song, oral tales, or written literature. It is transliterated as the letter O.
All rune pendants can be easily used with most common jewellery chains or leather strings. The attachment ring was carefully placed at the horicontal center of mass so that the pendants become never lopsided.
