Types Of Asbestos Fibers There are six types of asbestos minerals that occur naturally within the Earth's environment. The Environmental Protection Agency (EPA) has classified the types as such: Chrysotile : Chrysotile is one of the most common and most dangerous forms of asbestos found within our Earth. This type of asbestos accounts for approximately 90 percent of commercially-used asbestos in the world. Chrysotile asbestos fibers are long, white, and curly. Amosite : Amosite asbestos is recognized by its straight fibers and brown color. Amosite asbestos contains iron and magnesium, and was most used within different types of insulation products.

Chrysotile Chrysotile or white asbestos is the most commonly encountered form of asbestos, accounting for approximately 95% of the asbestos in the United States and a similar proportion in other countries.

- The translucent honey-yellow to greenish or brownish yellow chatoyant chrysoberyl which, when cut with a domed surface (cabochon) show a mobile streak of light are called as cymophane or cat's eye chrysoberyl. cat’s eye is a band of light that runs length wise from one end of the stone to the other.

What is Asbestos? Actinolite Asbestos – As a sub-classification of the amphibole asbestos, actinolite asbestos has a consisitency that is similar to the other forms of asbestos in this subset. It is mostly magnesium, and is very rare. The colors range from white to a very dark brown.

- Apple green chalcedony that derives its color from nickel is chrysoprase. Ranging from nearly opaque to nearly transparent, its color spectrum includes olivey, to nearly pure greens of medium tone. Very fine, highly saturated pieces have been successfully misrepresented as Imperial jade. Most chrysoprase sold today comes from Australia.

- General Definition. Asbestos is the name of a group of highly fibrous minerals with separable, long, and thin fibers. Separated asbestos fibers are strong enough and flexible enough to be spun and woven.Asbestos fibers are heat resistant, making them useful for many industrial purposes.ypes of Asbestos. There are two general types of asbestos, amphibole and chrysotile. Some studies show that amphibole fibers stay in the lungs longer than chrysotile, and this tendency may account for their increased toxicity (harmfulness to the body).

CHRYSOCOLLA The chrysocolla designation is applied because the chrysocolla content is responsible for the color, which is the selling point for these gemrocks. The chief difference between chrysocolla and the silica-bearing (etc.) chrysocollas relates to their effective hardnesses (1½ - 3½ versus ~7, respectively).

- In nature talc does not exist in its’ theoretical form or purity, but a small fraction of Mg and Si atoms can be replaced by iron (Fe), aluminium (Al) or nickel (Ni). Typically, the colour of talc stones is pale green or white, but the colour can vary from pinkish to dark green. The surface of talc stone has slippery feeling and pearly lustre. The unique fine structure of talc makes it ideal filler for protective coatings: Talc’s surface is electrically neutral, which makes talc highly hydrophobic, thus water.repellent. Talc’s particle form is platy, which is important for an optimum filler packing in the paint film. The platy particles also create a.good.barrier against

Chrysolite - The Golden Green Counsel of God Chrysolite is from the Greek chrysolithos meaning a precious stone of golden color. It comes from chryso meaning precious things made of gold, and lithos meaning of building stones. Peridot is the gemstone form of Olivine or Chrysolite and possesses a much richer green color. Mg-rich Olivine has been discovered in meteorites, on the Moon, and on Mars. Chrysolite and Olivine in general are a very abundant, but gem quality Peridot is rather rare.

Chalcocite Chalcocite, copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster. It has a hardness of 2½ - 3 on the Mohs scale. It is a sulfide with an orthorhombic crystal system. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning copper. It is also known as redruthite, vitreous copper and copper-glance.

Daily Wire Tip: Purple Turquoise and Turquoise Facts Answer: Hey Pat, I am sorry, but there is no natural purple turquoise. Turquoise is a hydrous phosphate of copper and aluminum, both of which cause the blue to green color. The natural color of turquoise ranges from chalky white to a yellowish green.Of course this leads into yellow turquoise, which is a natural material, but an extremely rare form of turquoise.nswer: Hey Pat, I am sorry, but there is no natural purple turquoise.

What is Asbestos? 1 Amosite, is called brown asbestos, is an “amphibole” from Africa. 2  Amphibole rocks have long, jagged, needle like fibers that are considerably dangerous if inhaled. 3  Crocidolite, or blue asbestos, is an amphibole rock found in Africa and Australia. 4  Blue asbestos is commonly considered the most dangerous type of asbestos.here are six different varieties of asbestos, but the three most common are: 1  Chrysotile, also known as white asbestos, originates in Canada. 2  It is from a “serpentine” rock, which means its fibers are curled and less sharp, pose fewer threats than other types of asbestos and is the type most often used industrially.

Guide to Gemstones The shimmer, which is called schiller or adularescence, is caused by the intergrowth of two different types of feldspar, with different refractive indexes. Moonstones come in a variety of colors. The body color can range from colorless to gray, brown, yellow, green, or pink.The clarity ranges from transparent to translucent. The best moonstone has a blue sheen, perfect clarity, and a colorless body color.nother related feldspar variety is known as rainbow moonstone. In this variety of labradorite feldspar, the sheen is a variety of rainbow hues, from pink to yellow, to peach, purple, and blue. Sometimes one gem will show all these colors. Fine moonstone is quite rare and becoming rarer.

Citrine As the distribution of color of amethyst is very different from that of most natural citrine, a heat treated amethyst is easily recognized: the yellow color is most intense in the tips, and the color might be more concentrated under the r-rhombohedra or patchy.

- 1 The gemstone's principle color is a reddish brown and the red variety called Pyrope is the best known garnet. 2  Garnet is not a specific gemstone. 3  Rather, it is a group of common silicate minerals that have similar structures and components. Many of these gemstones are a deep yellow, but can be light or dark yellow, a golden orange and a brown orange. 2  Citrine is a transparent quartz that gets its yellow color from iron. 3  It usually has excellent clarity and few inclusions.

ASBESTOS Asbestos is the name given to a group of minerals that occur naturally in the environment as bundles of fibers that can be separated into thin, durable threads. These fibers are resistant to heat, fire, and chemicals and do not conduct electricity.erpentine asbestos includes the mineral chrysotile, which has long, curly fibers that can be woven. Chrysotile asbestos is the form that has been used most widely in commercial applications. Amphibole asbestos includes the minerals actinolite, tremolite, anthophyllite, crocidolite, and amosite.

Pyrite Hand-specimens of pyrite are usually easy to identify. The mineral always has a brass-yellow color, a metallic luster and a high specific gravity. It is harder than other yellow metallic minerals and its streak is black, usually with a tinge of green.he only common mineral that has properties similar to pyrite is marcasite, a dimorph of pyrite with the same chemical composition but an orthorhombic crystal structure. Marcasite does not have the same brassy yellow color of pyrite.
