I have compiled a list of sources for the elements that are available to the amateur chemist. Neodymium will be discussed here.   


Neodymium is one of the more reactive rare earth metals. It forms one oxidation state, +3, and has the unique property of color-changing salts. A solution of neodymium chloride, pink in sunlight, may appear light grayish-yellow in fluorescent light. Neodymium oxide ranges from blue to purple to pink.


In element form: Neodymium magnets contain about 14% neodymium. Mischmetal has a small amount of neodymium in it.


In compound form: "Daylight" incandescent light bulbs often use neodymium oxide to make them bluish (fluorescent) or purplish (incandescent or sunlight) colored. The color change indicates the presence of neodymium.


Here is my sample of neodymium. It is a neodymium magnet.
