Explore one of the finest public displays of fluorescent minerals in the world. Our main display, 32 feet long, features hand-sized to large (up to 2.5 ft) specimens of the local fluorescent minerals, all brightly glowing in rich hues of red, green, orange, yellow, and blue. For brilliance and variety of color the local minerals remain unsurpassed and have been aptly described by one visitor as “fireworks frozen in the dark.”
A series of small display cases on the opposite wall houses many of the less-common fluorescent minerals of the area, for the benefit of collectors who wish to know what these minerals look like, and as an aid to identifying specimens in their own collections. More than 90 different fluorescent minerals have been found within the Franklin-Ogdensburg area, and many of them are on display here.
