These minerals have a hidden property! In normal conditions they cannot be seen, but in the dark under a UV lamp they come alive. Read more.
Very special fluorite that changes from green to purple under the UV radiation of daylight! A fantastic phenomenon that very few minerals possess.
What is Fluorescence in Minerals?
Fluorescence in minerals is a process in which a mineral gives off light when exposed to ultraviolet light. This glow, which often appears in different colours, depends on the type and composition of the mineral. The colour of the emitted light can be completely different from the colour the mineral has in daylight.
How to detect Fluorescence in Minerals?
Identifying fluorescence in minerals is simple. First, you need to have an ultraviolet light source. This can already be done through a simple UV lamp. If the mineral is fluorescent, it will glow immediately when UV light falls on it. If your mineral gives off no glow, it means it has no fluorescence. This works best in a dark environment without a white background.
