Having a weakness along a specific plane will allow a mineral to cleave, meaning it can break along that specific plane into flat surfaces. This property of cleavage is a result of the internal structures of the mineral being weaker along certain planes, allowing it to break cleanly. Minerals with cleavage are often used as gemstones because of their ability to be cut and polished into smooth, lustrous surfaces.
cleave
Quartz is a mineral with a crystal structure that lacks planes of weakness along which it could cleave. Its atomic structure forms a three-dimensional network, allowing it to fracture instead of cleave when broken. Cleavage occurs when a mineral's crystal structure has planes of weakness that allow it to break along certain directions with smooth, flat surfaces.
The name of a mineral that splits along flat surfaces is called mica. Mica's cleavage planes allow it to be easily split into thin sheets.
Sulfur has a conchoidal fracture, resembling the curved shape of a seashell when broken. It does not have a distinct cleavage because its atomic structure does not easily allow the mineral to break along specific planes.
Mineral luster is classified based on how light reflects off the surface: metallic luster shines like metal, while opaque luster does not allow light to pass through, appearing dull or earthy.

In some cases, yes. Depending on the laws of the state and the terms of the property deed, mineral rights may be subject to eminent domain or other legal processes that allow them to be acquired without the owner's consent. It's important to understand the specific laws and regulations regarding mineral rights in your area.

The laws regarding having wild animals as pets varies from state to state and province to province and country to country. Some states are specific as to what animals you can't have and then others allow pretty much anything else.
