Fluorescent Minerals of New York State

New York hosts many varieties of minerals that fluoresce under ultraviolet light.

Fluorescence is the property of a mineral to emit visible light when activated by ultraviolet light (UV). The light emitted by the lamps in this display reacts with certain chemical elements in the composition of the mineral and cause the mineral to glow. This visible light is often very colorful and bright (red, yellow, orange, green, blue) and sometimes, very different from the characteristic, daylight color of the inactivated mineral. Some minerals continue to glow after the UV light is turned off; this property is called phosphorescence. Spectacular fluorescent minerals from different New York State locations are presented in this display case.
