Montmorillonite in Quartz

Montmorillonite is a clay mineral, not typically represented in mineral collections. The mineral name denotes the type occurrence at Montmorillon, France (Mauduyt, 1847). These specimens come from the a pegmatite in California better known for its fine morganite specimens. They are refreshing contrasts to a typical clay sample. Montmorillonite forms white to pink filaments and clouds in quartz, and imparts a pastel pink coloration different from that seen in rose quartz crystals. This is a good example, a floater, but unfortuantely with one chipped termination.
