Amethyst: Amethyst due to iron, manganese and other minerals and the formation of beautiful purple, the main color of lilac, purple, dark red, dark red, purple, blue and purple color, with deep purple and red is the best, too pale purple is more common. Natural amethyst will usually have a natural ice crack or white clouds of impurities. Amethyst is widely distributed in nature, the main origin of Brazil, Russia, South Africa, Madagascar. China's Shanxi Amethyst has one hundred years of mining history, mainly distributed in the Mount Wutai, Mt. Hengshan, and Liangshan Lu Yanbei area.
Lan Shanhu: blue coral is mainly composed of calcium carbonate, magnesium carbonate, ferric chloride and other inorganic compounds and keratin and other organic substances, and containing strontium. Manganese and other 10 kinds of trace elements and 14 kinds of amino acids, hardness of 3.5 degrees, no acid resistance, coral is a very picky about the environmental conditions of the sea life, growth in the tropical sea reef water depth of 200~2000 meters, the water temperature is about 13 degrees in between and comparison of stationary and clear waters from the larval settlement after 10~12 years before sexual maturity, growth is extremely slow, 20 years to one inch, 300 years to grow one kilogram, yield rare, low temperature, water is deep. Picking is very difficult, it is extremely rare and precious.
Pictographic stone: the so-called pictographic stone unearthed refers to it, after artificial grinding belongs to the art decoration range. Because the stone is very rare, so, the history of the Tibetan stone are classified as the first choice. At present, many of the quarry and businesses to meet the needs of the market, the image of the human, and even the use of high-tech means of processing. For example, agate cut surface with a laser produced image, chemical and color, etc., involved in the stone is very difficult to identify. Some good hieroglyphic stone reservoir because of ignorance, deliberately rough patina burnish drops, but put a thousand pounds in the works not worth a penny.
Fossil wood: the wood of a tree that has been rapidly buried in the ground after millions of years or more before it is quickly buried. It retains the structure and texture of the trees. The color is brown, yellow, brown, red brown, gray, gray and black, polished surface with glass luster, opaque or transparent, because part of fossil wood texture showing jade texture, also known as the jade tree. Produced in Xinjiang Qitai silicified petrified wood is 38 meters long, the root diameter of 1.2 meters, is the extremely rare giant fossil wood, the world's longest silicide.
Stalactite: also known as stalactite, which often require thousands of years or hundreds of thousands of years. Due to the formation of a long time, the stalactite has important research value of ancient geological investigation. Guangxi, Yunnan is the most abundant resources in China stalactite provinces, by the middle of the stalactite luster clear, strange shapes, has a very high appreciation value.
Lingbi stone natural formation of the Unicorn: a kind of stone. The so-called pictographic stone refers to pure natural form without artificial stone polishing with modified pictographic character. Because the stone is very rare, so, the history of the Tibetan stone are classified as the first choice. We in Anhui County of Lingbi province is rich in Lingbi stone, is one of China's traditional ornamental stone, early in the Warring States period has been as a tribute. This work has been on display in World Expo in 2010, by everyone's favorite.
Fluorite: general is granular or blocky, with glass luster, purple or green for more. Fluorite in the ultraviolet or under the cathode - ray irradiation often blue green fluorescence, its name is based on this feature. Can be used as a jewel in the night, but there is harm to the human body. Jewelry industry often according to the process of fluorite and color features to the classification of fluorite varieties, according to the process uses, fluorite can be divided into two kinds of gem and jade. Gem: single crystal, transparent, fresh color, because of low hardness, rarely used in jewelry, and for viewing and collection of jade: granular or fibrous aggregates, translucent, single color or colors and white banded distribution. Used for carving or made craft ornaments. Fluorite can be divided according to the common color of green, purple, blue and other varieties.
Wood: also called Jade jade tree, silicified wood tree jade white jade is jade. It belongs to the wood, but also because of its crystal clear appearance and different from ordinary wood. With the special status not only show wood jade jade rich, and beautiful rings and bark records provide some vicissitudes of life, the information in the. Not only have economic value, ornamental value and scientific research value is very high. And its non renewable gem quality shows: it is expected in the next ten years, the value of dozens of times, so there is a high collection value.
Causes: in the long course of history, the vast primeval forest is broad nature buried. In high pressure and low temperature and anaerobic environment soaked in saturated solution of silica, carbon in trees is gradually replace silica retains some of the original, and some characteristics of trees, into some mineral elements of surrounding rock, the formation of the colors, which is also called silicified wood, petrified wood. Then the long geological period, in the changing of temperature and pressure in the silicified wood wood had different metamorphism, re crystallization, the main component that is converted to opal chalcedony, jade tree, also called wood jade. The specific formation of the age, because of the limitations of the study of wood, there is no complete discovery.
Collection value: the formation of the tree of jade and its harsh geological environment conditions, the probability of the formation of ancient fossils is only one part of a million, to form a lower probability of the tree of jade.
Because of the special nature of fossil non renewable, the world is one of the mining, underground storage...
