Many of the light-colored silicate minerals in low-iron igneous rocks (particularly granites, syenites, and granite pegmatites) can fluoresce.Īlbite and the potassium feldspars typically fluoresce in shades of red, which may range from barely perceptible to moderately bright. Granites, syenites, and granitic pegmatites with a high concentration of fluorescent feldspar and low iron content can also glow. They are rocks with a high concentration of calcite, which are limestone, marble, and travertine. Rocks that contain fluorescence minerals can glow under UV light. ![]() Fluorescent minerals combined with other rock-forming minerals produce rocks that glow. The answer to why some minerals and rocks glow is hidden in their chemical composition.Ī list of specific elements (activators) can be an essential part of a crystal structure or just an impurity. Mineral and rock glow is scientifically explained by the fluorescence phenomenon. If you are looking for the best UV light for rockhounding only, I and other members of the reputable Facebook group about rockhounding recommend buying Convoy 8+ UV light(Amazon link). Rocks & Minerals That Glow Under UV Light & Black Light What minerals are needed? Are they rare? What kind of light source should you use? No doubt, you will be surprised how easily this phenomenon can be achieved. Reading this article, you will find how to observe mineral glow or fluorescence at home. Let us guide you through this miracle of nature! You can observe this phenomenon even at home! Unlike some other physical and optical phenomena, which can be hardly observed without any specific microscopes or chemical solutions, fluorescence can be easily seen even at home with the help of a UV flashlight. Some of them can glow a particular color, but others can be in a rainbow of possible hues. ![]() The most common minerals and rocks that glow under UV light are fluorite, calcite, aragonite, opal, apatite, chalcedony, corundum (ruby and sapphire), scheelite, selenite, smithsonite, sphalerite, sodalite. New colors are so bright and vivid that it is hard to say they are natural. This phenomenon is reinforced by the colors observed. Minerals and rocks can completely change their colors by being subjected to UV light or black light. Minerals and rocks, which glow under ultraviolet light, are usually perceived as a miracle. ![]() As an Amazon Associate, I earn from qualifying purchases with no additional costs for you.
