WebPegmatites are Nature’s treasure chest of gems and minerals and are a rockhound’s best friend because they provide him with a happy hunting ground for many beautiful gems and minerals. Some pegmatites contain an unusual assemblage of sometimes as many as 150 different minerals. WebMinerals are composed of atoms, which in turn contain electrons at specific energy levels. Ultraviolet light is an energy source. When we shine an ultraviolet lamp on a mineral that fluoresces, the atoms that make up the mineral absorb energy from the light by moving electrons to higher energy levels.

WebMinerals that exhibit fluorescence are known as "fluorescent minerals". Fluorescent minerals contain particles in their structure known as activators, which respond to ultraviolet light by giving off a visible glow. … http://webmineral.com/data/Eucryptite.shtml
