Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or nonmetallic. Minerals that are opaque and shiny, such as pyrite, have a metallic luster. Minerals such as quartz have a nonmetallic luster. Luster is how the surface of a mineral .

Quartz vs. Quartzite. So, quartz and quartzite are not the same thing, even though both of them contain the mineral quartz (thus, the similar names). But what are the actual differences between the two? Are they comparable to each other in terms of durability, functionality, aesthetic appeal, and price?

Quartz sand could provide nucleating sites for secondary iron minerals and overcome the unfavorable influence of a low Fe3+ supply rate in the initial bioleaching stage (0–24 h). Because it was conducive to accelerating the initial mineral precipitation, quartz sand could improve bioleaching efficiency.

Gold in Quartz. While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered through the quartz, often filling cracks and openings in the vein material.
