After-hours Exploration at the Langsdon Mineral Collection
The Langsdon Mineral Collection hosted a special "Night in the Museum" event for members of the Richmond, Troy, Fort Wayne and State Line gem and mineral clubs.
During this event, 25 club members visited the collection after hours, which allowed them to explore the collection using not only incandescent lighting, but also both long and short wave UV. Club members were amazed at the wide variety of fluorescent specimens scattered among the 27 display cases.
The group was also able to view the items in storage, which are not currently displayed, including a stunning piece of Stilbite with Apophyllite clusters from India.
Many of the specimens are newly discovered minerals from recently-opened mines in India, China and Pakistan. Other specimens are from historic mining areas, which are now closed to collectors. The collection contains pyrite, galena, quartz, tourmaline, apophyllite, stibnite and rhodochrosite, among many others. Each sample is labeled with the mineral type and place of origin.
