A mineral glows under ultraviolet light.  A mineral has hexagonally shaped crystals.  A mineral is warmed and smells like rotten eggs.

Explanation:

Any structural, physical and/or chemical properties of a mineral can help in its identification. The shape of crystals, light emission under ultraviolet light and release of smell like rotten eggs upon heating are some of the characteristic features that can help in identification of a mineral.  However, the location of its occurrence and natural or man made origin may be shared with other minerals as well and can not serve in identification.
