The luster (or lustre) of a rock is a description of the way light interacts with the surface of a crystal, rock, or mineral. The term is also used to describe other items with a particular sheen.
The sparkle is the reflection of light off the mineral crystal faces or cleavage surfaces.
Texture is the word used to describe a rock's constituent mineral size and arrangement, visible on a freshly fractured surface. Because a rock's surface can be weathered to a smooth or polished surface, the way it feels is not usually included in a description of texture.
UV light does interact with earth surface. But only in areas where there is absence of ozone layer.
Well surface mining is when mineral deposits are located near or at the surface
Luster (or Lustre) is a description of the way light interacts with the surface of a crystal,rock or mineral - For example a metallic lustre or silky lustre.

Mineral
Metallic luster is a mineral description, referring the interaction of light with the crystal surface, in this case, the look of shiny metal. Simply, the shininess of a metal.
d. on the surface of the Earth
The surface of a crystal is called a flat face or a facet.

For simple identification purposes you should ask: what is the hardness of the mineral compared to other minerals; what is the color (streak) of the mineral when scratched on an unglazed porcelain ceramic surface; and does the mineral react with dilute hydrochloric acid or vinegar, indicating whether or not it's a carbonate mineral. Other identifiers would be the mineral's specific gravity, lustre, and crystal classification.
The sparkle is the reflection of light off the mineral crystal faces or cleavage surfaces.
Way light interacts with surface i.e. shine.
There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
