china silver necklace Can be used to makenight pearlgem-fluorite

Fluorite is a mineral composed of calcium fluoride (CaF2), also known asfluorite”, which contains many impurities. The crystals are mostly cubes or octahedrons, and the aggregates are clusters or blocks. The pure ones are transparent and colorless, and the ones with impurities are often green, blå, lilla, rose red and other colors. Appears glass luster, transparent to translucent. Hardness 4, density 3. 18g/cm3. It can emit purple fluorescence under cathode rays and ultraviolet rays; it can emit phosphorescence under sunlight. Among the fluorite minerals, there are a small number of those that can emit strong phosphorescence, which can be used to make night pearls and become valuable luminous gems.

Fluorite in nature is mainly formed by hydrothermal action and is widely distributed. The types of fluorite deposits include skarn, hydrothermal, stratification and sedimentary types, among which hydrothermal types are the majority.

According to incomplete statistics of relevant data, the world’s total reserves of fluorite are about 900 million tons, and China accounts for about 35% of the world’s reserves, making it one of the countries with abundant fluorite reserves in the world.

Almost all provinces in China have found fluorite resources, among which gem-grade fluorite is mainly distributed in Zhejiang, Jiangxi, Fujian, Inner Mongolia, Henan, Hubei, Hunan, Guangxi, Guangdong, Sichuan, Guizhou, Qinghai, Xinjiang and other places. The news that the by-product mineral fluorite of a non-ferrous metal mine in northern Guangdong Province can glow at night (ie, has aphosphorescence effect”) has been reported more than 10 years ago. Recently, when thePearl of the Nighthas spread across the country, the “210kg Giant Night Pearlreported by theGemstone Weekly” (juli 25, 2002) has been reported in Beijing. 800kg of fluorite ore is processed.
