Sardonyx keychain

Carry your keys with style and protection. Large round sardonyx disc set into sterling silver with stainless steel keychain. 
Sardonyx is a semi-precious gemstone symbol of strength, protection, courage, and clear communication. Its name blends its two natural components: sard (a reddish-brown chalcedony) and onyx (layered, parallel-banded chalcedony). It is celebrated as the oldest of the three traditional August birthstones, alongside peridot and spinel.
