"Mini Heart" crystal mine
Fisheye stones, Hubei stone, red silicon calcium manganese ore, which are highly localized mineral crystals, make the Daye Fengjiashan Mine famous in the domestic and international mineral crystal industry.

Beautiful and moving fisheye stone
Fisheye stone is a potassium-calcium silicate mineral containing crystal water. Because of its special and rare silicon tetrahedral layer structure, the luster scattered from the cleavage surface is pearly, similar to the reflection of fisheye. Color, it is called fisheye stone. The fisheye stone can be divided into two sub-species of fluorine fisheye and hydroxy fisheye depending on its fluorine and hydroxyl groups.
According to Jin Jingfang, a member of the China Association of Natural Science Museums and director of the Huangshi Xinfu Geological Minerals Exhibition Hall, although there are a few countries in the world that produce fisheye stones, there are not many commercial values, and there are fewer gemstones. In the European and American international mineral market, fisheye stone is used as a gemstone for viewing and collecting. Pune, India, is world-famous for producing light green and colorless transparent columnar fisheye gem minerals. In recent years, the crystal form and color of the output of Qinghai Haixi Prefecture in China are similar to the ornamental specimens of fisheye in Pune, India, and a small number are sold to Xi'an and Beijing.
The hydroxy fisheye stone of the Fengjiashan Mine is not only different from the fisheye stones of the above countries and regions. Comparing the mineral crystals produced by its symbiotic combination, the fisheye stone of the Fengjiashan Mine is more colorful and more attractive!
The crystal form of the hydroxy fisheye in the Fengjiashan Mine is mainly plate-shaped, as well as columnar, and irregular granular aggregates, hydroxy fisheye and penetrating (hard) gypsum, wollastonite, calcite, dolomite, and recrystallized. Stone, toxic heavy stone, black shale, epidote, zeolite, crystal, scheelite, porphyrite, chalcopyrite, pyrite, red silicate, manganese ore, Hubei stone and other mineral crystals, sometimes a mineral cluster There are as many as ten kinds of minerals in seven or eight, which grow together, are rich and colorful, are very ornamental, and have multiple growth characteristics, and the research value is extremely high.
"Feng Jiashan's fisheye stone can be described as a variety of jasper inside, giving people a sense of beauty. Especially with the red silicon symbiosis, plus the embellishment of Hubei stone, often showing light, elegant, subtle and not arrogant." Jin Jingfang said.
Internationally renowned Hubei stone
"Because of the mineral component analysis, we only made conclusions based on the error line graph. We missed the glory that the Chinese should declare new minerals, and became the honor and contribution of foreigners. This is indeed a piece. It is always regrettable.†When talking about Hubei Stone, which is the only rare ore produced by Fengjiashan in the world, Jin Jingfang, the first discoverer, always sighs when he thinks about it.
Jin Jingfang could not forget the day of July 1997. He once again came to the state-owned Fengjiashan Copper Mine. Previously, he came to Fengjiashan many times and failed to go down because of mine management reasons. This time, Jin Jingfang finally persuaded the mine owner to pick up the first batch of mineral crystal specimens in Fengjiashan. Since then, he has successively collected some crystals from the mines of Fengjiashan. One of them appears to be black, which is brown-red in the form of slab-shaped, bundle-shaped, sometimes spherical, aggregate crystals. His attention, later identified in the China University of Geosciences, is that this is a kind of amphibole, not a new mineral.
In order to make a living, he traded a portion of the crystals in his hand for a part. In 2003, in the exchange with Hunan's specimens, Jin Jingfang learned that in the foreign mineral collection market, some people called the mineral crystal that they had discovered as “Hubei Stoneâ€, and claimed that it was a newly discovered mineral. Jin Jingfang is very puzzled. Is this mineral crystal called "Hubei Stone" not the kind of mineral crystal that he discovered in the past?
Jin Jingfang made a special trip to the Chinese Academy of Geological Sciences. Mr. Wang Liben, the representative of China on the New Minerals and Minerals Nomenclature Committee of the International Mineralogy Association, told him that “Hubei Stone†was indeed declared by Canadians. When the mineral crystals flowed into the international market, Canadian buyers discovered its value and identified it at the Canadian Mineral Research Center and found it to be a new breed in the mineral family. Because the center experts only know that the ore comes from Hubei, China, they named it “Hubei Stoneâ€. It is said that there are only two stone species named after the name of the center in the center, and the other is the "fragrant stone" produced by Xianghualing, Chenzhou, Hunan.
Glamorous red silicon calcium manganese ore
The red silicon calcium manganese ore produced by Feng Jiashan and the Hubei stone, like a pair of brothers and sisters, are often associated with each other.
Red silicon calcium manganese is produced in hydrothermal and contact metamorphic deposits and is not an important industrial mineral. Found in China, South Africa, the United States, Germany, Sweden, Italy, Mexico, Australia and even Japan. The earliest record of red silicon calcium manganese ore appeared in 1892. The red, silicon, calcium and manganese ore produced in the Kalahari manganese belt in South Africa has been the main source of this species in the world in the last century. It was not until the 1990s that the Fengjiashan Mine discovered a high-quality red-silicon-calcium-manganese ore that broke the monopoly of the South African origin. The red silicon, calcium, manganese ore produced in other producing areas in the world is inferior to Fengjiashan and South Africa.
According to reports, red silicon calcium manganese ore is mostly associated with pyrite, crystal, calcite, fisheye stone, wollastonite and so on. The crystals are columnar or plate-shaped, radial, needle-like aggregates, rose red and orange, glassy, ​​transparent to translucent. Colorful people are very collectible. Daye once had a piece of the best red silicon sold abroad for 300,000 yuan.
