The main distinguishing features of the square natrium are: dark blue, polycrystalline structure, low RI1.48, low SG2.28 floating in the heavy liquid of 2.65, red under Charles filter, and white substances distributed in it can be seen when magnifying.The color of lapis lazuli is similar to that of lapis lazuli. The main distinguishing point is that lapis lazuli is a combination of many minerals, with pyrite particles and calcite distributed in the shape of star or lump.As a kind of feldspar - like mineral, quadrate sodium aluminosilicate contains chloride.Because its
Suji stone, commonly known as shu ge lai stone, is a common jade in the market. It is also known as the "millennium stone". It is also the birthday lucky stone in February of the Gregorian calendar.In 1973, a large scale suji stone was discovered in South Africa.It became a commercial variety in the 1970s.The color of suji stone is characteristic of dark blue, red purple and blue purple, sometimes showing several different shades on the ribbons and spots.Suji stone is also often tan, pale pink and black, but these are rarely used in jewelry.Suji stone is usual
A white silicate mineral, an important zinc ore.The heteropolar mineral is found in the oxidation zone of the lead-zinc sulfide deposit.The upper limit of stability is 250°C, after which it is transformed into wollastonite.Heteropole ore and zinc ore similar, the difference is acid does not bubble.Usually also contains Pb, Fe, Ca and so on.Crystal water is lost when the temperature rises to 500°C;At higher temperatures, the water is lost and the crystal structure is destroyed. Introduction. Heteropolar ore is a component of calamine.It is a silicate mineral that
It is mainly found in the almond body of basic ejective rocks (basalt and diabase) and is symbiotic with zeolite and calcite.Less fertile calcareous metamorphic rocks alkaline intrusive rocks and mica peridotite. Introduction to the An overview of the Mineral name: Pectolite (compcat) Monoclinic Chemical composition: Na(Ca> 0.5mn <0.5)2[Si3O8(OH)], stable chemical composition, chemical analysis data: SiO253.80, FeO 1.00, MnO 0.12, CaO 33.20, Na2O 9.01, H2O 2.94, total 100.07.Mn - rich acushiolite is called manganese acushiolite. Identification characteristics: in hydrochloric a
Rhodochrosite is a carbonate mineral, which often contains iron, calcium, zinc and other elements. And these elements often replace manganese. Therefore, pure rhodochrosite is rare. The rhodochrosite is also a source of manganese for the production of iron-manganese alloys. They are usually granular, lumpy or kidney-like, red, and the surface is brownish black after oxidation. With a glass luster. Large crystal grains and transparent color can be used as gemstones. The fine, translucent aggregates of the particles can be used as jade carving materials. Introduction The r
shell is the mantle of a mollusk that lives near the water. It is a calcification that protects the soft parts of the body formed by the secretion of a special kind of gland cells of the mollusk.Compared with natural calcium carbonate, shell has unique multi-scale and multi-level "brick-mud" assembly structure, and has good toughness and strength due to its multi-stage layered structure. Shells consist of about 95% CaCO3 and about 5% organic matter. Chemical composition It is found that shell formation is a process of biomineralization, that is, the formation of org
Tortoiseshell is an organic gem composed of organic matter such as keratin and bone.Hardness: 2-3;Tortoiseshell shell, especially the back, for the amorphous body, was slightly transparent to translucent, waxy to grease luster. Material source Tortoise shell is an organic gem, composition: calcium carbonate;Hardness: 2.5;Tortoiseshell shell, especially the back, for the amorphous body, was slightly transparent to translucent, waxy to grease luster.During the making process, the ridges of the tortoise shell need to be removed. In addition, the main source of tortoiseshell tort
Conch Pearls, also known as Conch Pearls, are unique in that beneath their polished surface lies a unique, bright flame.This kind of flame is not only apparent from the outside, and it sometimes fine soft, sometimes warm and unrestrained, appears extremely noble.Another characteristic of the pearl is that it does not grow inside the mussel, but slowly forms inside the conch. The pearl-producing conch is found on beaches in Florida, Mexico, the Bahamas and the arnti peninsula in the Caribbean.They owe their existence entirely to nature, not to artificial breeding. Rar
Amber, is a kind of transparent biological fossil, is the pine cypress family, yunshi family, australopeia family and other plants resin fossil.Resin drip, buried in the ground for thousands of years, in the pressure and heat under the action of petrochemical formation, some of the internal bag bees and other small insects, qili abnormal.Amber is mostly formed by the resin fossilization of pinaceae plants, so it is also known as "pine resin fossil". Amber comes in a variety of shapes. The surface and interior of the amber often retain the grooves created by the f
Coal spirit, also known as coal jade.It has a bright pitch and metallic sheen.Black, dense, ductile.There are two kinds. One is a kind of high-grade coal, which is mainly composed of carbon c and is lighter than ordinary coal.The other kind is petrified very thorough, main composition is not carbon, density is bigger, than coal heavy, after carving processing luster is more beautiful.It's between the coal seams. Coal fine can be used to make arts and crafts, carving crafts and decorations, so some people call it carved paint coal.China's main producer is fu
