Pseudoboleite is much rarer than boleite from the Amelia Mine at Boleo, Mexico. This fine piece features two, lustrous, indigo-blue pseudoboleite cubes to 7 mm aesthetically set on stabilized clay matrix. Actually, the pseudoboleite is the 3-dimensional outgrowth upon boleite, a cube of which remains underneath the pseudoboleite accretion. Ex. Bill Larson Collection. Bill and Ed Swoboda spearheaded a mid 1970s mining project at the Amelia Mine.
