A definite chemical composition
Magnetism is a property that can be used for only a few minerals. Some minerals exhibit magnetic properties, while others do not. This property can be helpful in identifying and distinguishing certain minerals from others.
Magnetism is a unique property of minerals used in a compass.
Minerals in the ground are treated as real property, but, after removed from the land, they become personal property.
What property do minerals that glow under ultraviolet light display

Density is a quantitative property of minerals that can be measured by determining the mass of a mineral sample and dividing it by its volume.
Color is the least reliable physical property for identifying minerals because many minerals can have the same color but different compositions.

A primary property is one that all minerals possess, whereas a special property is found in only one or a few minerals.
Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.
