Rare Mineral Specimens are highly collectable items. If you are a mineral collector you should have those in your collection. Different minerals are said to have different properties, and for thousands of years, they have been made into rings, bracelets, amulets, brooches & pendants to capture their magic. A popular theory is that minerals contain vibrational energy. By placing minerals within a person's aura it is possible to change the vibrations of that aura. They can help you absorb negative thoughts, fill you with courage and confidence or improve your memory.
