You can google ZIRKUS. Apparently they quit making their silver jewelry around 2003. They made mostly circus animal type sterling jewelry. This is a single earring. It is slightly over 2 1/2\" long and approximately 1 1/4\" wide. Maybe you have a mate or like one of a kind. It could also be used like a lapel type pin with a wider back. Please look at the photos and specifics and email any questions. Thanks for looking at this unique piece.
