Crystal form or habit
WebFluorite Crystal can crystallize in isometric cubic habit, which means it forms cubes or octahedrons, or more complex shapes that are symmetrical in all directions. Fluorite Crystal is colorless and transparent in its pure form, but it can have various colors due to impurities or exposure to radiation.

WebCrystal habit, or morphology, is a crucial attribute of powdered materials that affects the ease with which a pharmaceutical formulation can be pressed into a tablet. In particular, equidimensional crystals are usually preferred in the industry as they have better handling and processing characteristics such as flowability and compatibility. WebQuartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz than any other mineral. Although the Feldspar s as a group are more prevalent than Quartz, as an individual mineral Quartz is the most common mineral.
