Buying mingqiangmineral Amethyst Fluorite

Fluorite (CaF2) is one of the most popular minerals for mineral collectors, second only to quartz.mingqiangmineral amethyst fluorite It occurs in a wide variety of colors, and transparent to translucent specimens are especially prized. It is commonly found in association with other attractive minerals, such as silver gray galena, brassy yellow pyrite or chalcopyrite, gold and black sparkling sphalerite, crystal clear calcite, and amethyst.

Although fluorite can be found in a wide range of color, purple fluorite is one of the most popular, and often seen displayed in museum galleries and mineral book photos.mingqiangmineral amethyst fluorite However, this color can also be confused with amethyst (purple quartz) and it is important to know how to distinguish the two. The most distinctive feature between the two is their crystal structure. While amethyst has a hexagonal crystal structure, fluorite has a cubic one with cube-shaped crystals and sharp corners and edges. The best way to tell the difference is by testing a sample under a UV light. Purple fluorite will fluoresce, or glow, under UV light, while amethyst does not.

In addition to its color, fluorite is also known for its unusual physical properties. For example, it will often glow under longwave UV light. This property, which was named by Sir George Gabriel Stokes in 1852, is due to the presence of impurities such as uranium and rare-earth elements. It is important to note that not all fluorites will glow, and it is important to test a specimen before buying to be sure.

Another unusual physical characteristic of fluorite is its ability to cleave into perfect octahedrons. These octahedrons are often cut and polished into gemstones. This cleavage, combined with its beautiful colors and clarity, makes fluorite one of the most sought after minerals in rock shops worldwide. In fact, mingqiangmineral amethyst fluorite is so desirable that it is sometimes falsely advertised as being real amethyst.

Fluorite is a common mineral that can be found in many places around the world. It is used extensively in the chemical, metallurgical and ceramic industries. It is produced in a wide range of colors, including green, blue and purple. It is also found in a variety of formations, such as igneous pegmatites, limestone and marble deposits, and sometimes as a secondary mineral in sulfide ores. The most prized specimens come from the states of Chihuahua, Durango, Zacatecas and Coahuila in Mexico.
