Fluorescence in geology is a term used which refers to a minerals ability to absorb certain wavelengths of ultraviolet light and emit it at a different wavelength. While some minerals may look spectacular and colourful in natural light, others may look dull, bland, boring and uninspiring. However, some minerals have the ability to fluoresce when exposed to certain wavelengths of ultraviolet lighting. When hit by a uv light, fluorescent minerals absorb the light and emit it at a different wavelength. This causes them to appear in a drastically different and often extremely luminous and vibrant colour than it would appear in sunlight. In this section, you will be able to find many large display size mineral specimens which have fluorescent capabilities. All the specimens we photographed using an 8 watt fluorescent lamp.
