Fluorescent minerals are popular for collectors worldwide.
These minerals exhibit luminescence such as fluorescence, phosphorescence, triboluminescence, and thermoluminescence.
Ultra violet lights ,known as black lights are required to show luminescence of the mineral.
Long wave (LW)and short wave (SW) may be required to display the mineral at its best.
60 watts bring out strong luminescent colours and 95 watt triple ultra wave brings out best colours but these costs around $2000 so must collectors use domestic ultraviolet lamps around $100 to show off their collection.
Popular Fluorescent minerals with luminescence include Calcite, Agrelite, Gypsum, Flourite, Argonite, Apatite, Diopside,Quartz,,Rubelite,Ruby corundum,Scheelite,Selenite,Sodalite,Topaz, Scapolite,Tourmaline, Willimite,Wollastonite,Zircon and Chalcedony .
