Neodymium creates a beautiful bright pink/purple crystals. Nd:YAG (neodymium-doped yttrium aluminium garnet) is a crystal that is used in many different ways, one of which is in the military. It is the most common laser used in laser designators and laser rangefinders. I hope you’re never at the end of one of these in use. If you are, prepare yourself for a greater threat. Another use for Nd:YAG lasers are in medicine, it is used to treat skin cancers, and used for laser hair removal; industrial uses for Neodymium consists of cutting and welding steel and other metals.
Neodymium, iron and boron when formed into an alloy make the strongest permanent magnets in the world till now. Neodymium magnets look sturdy but are hard and brittle. It has a structure that resembles ceramics which is easily cracked and chipped. The discovery of this alloy allowed things to get small; especially mobile phones, microphones, loud speakers and electronic instruments. Almost all new electronic devices use Neodymium magnets in one way or another.
Neodymium is a toxic metal. Try not to get it in your eye; it will result in serious damages. Also try not to expose yourself to Neodymium dust as inhaling it causes lung embolisms (accumulation that causes blockages in blood vessels); this can also cause damage to the liver. The dust of a Neodymium magnet is extremely flammable so avoid machining or drilling into them. By chance you know someone who has a pacemaker, I plead you not to go near them with a Neodymium magnet... you can work out the rest.
