After World War II, Lisker & Lisker Inc. (formerly Providence Jewelry Co.) changed its name to Jonette Jewelry Company and started marking their jewelry with the initials "JJ" in 1970 which became their registered trademark. The Jonette Jewelry Company made mostly novelty/figural pins. They just closed in 2006 so their jewelry will become more valuable as it becomes harder to find.
