POLLUCITE Meaning and
Definition
-
Pollucite is a mineral that belongs to the zeolite group. It is a rare and valuable crystalline rock that has a chemical formula of (Cs,Na)_2Al_2Si_4O_12·2H_2O. The name "pollucite" is derived from the Greek word "pollux," meaning very pale, and was given to this mineral due to its colorless or white appearance.
This mineral is typically found in granite pegmatites, which are coarse-grained igneous rocks. It forms as small crystals or large, well-formed prismatic crystals that have a vitreous to resinous luster. Pollucite has a Mohs hardness of 6 to 6.5, making it relatively hard compared to other minerals. Its specific gravity ranges from 2.8 to 2.9.
What makes pollucite particularly noteworthy is its high concentration of the rare alkali metal cesium. It is one of the primary commercial sources of this element, which has various technological applications. Pollucite crystals that are rich in cesium can be valuable for extraction purposes.
In addition to cesium, pollucite may also contain trace amounts of other elements like sodium, potassium, and rubidium. It is important to note that pollucite is primarily known for its commercial value as a cesium ore, rather than its aesthetic qualities. Nevertheless, in some cases, it may be utilized in the creation of gemstone carvings or as specimens for collectors due to its unusual crystal form and rarity.

Etymology of POLLUCITE
The word "pollucite" originates from the Greek word "pollux", meaning "much" or "abundant". It was named as such due to its high cesium content. Pollucite is a rare mineral composed primarily of cesium, aluminum, silicon, and oxygen. It was first discovered in 1846 by Gustav Rose, a German mineralogist, and crystallographer.
