JMS as a group company recently added a new group member. SSG Solnhofen Stone Group joined JMS on January 1, 2013. Now JMS is representing five Jura quarries and factories. SSG did hold former SNS, Solnhofer Natural Stone LLC San Francisco as its daughter company in the U.S. Now all activities in the U.S. are merged with JMS. This makes JMS the largest source for Jura limestone and Solnhofen slate.
