These very unusual pseudomorphs came only from one find in California in the mid-1970s. "Leonhardite" has completely replaced the laumontite, retaining its form perfectly, and in fact this is a very large crystal from the find, complete all around and terminated and therefore quite significant. The mine was operated by Union Carbide. 14.2 x 1.2 x 0.8 cm
