How to dish turquoise?

First of all, in the case of frequent wear or play:

In this case, the maintenance is relatively simple, because turquoise comes into contact with human skin during wearing or playing, and it will unconsciously be contaminated with a layer of oil secreted by the human body.

These oils will form a thin protective film on the surface of turquoise to prevent turquoise from losing water too quickly. At the same time, oil and sweat will slowly penetrate into the interior of turquoise, making the color of turquoise change. This is a wonderful process.

Of course, in the process of color change, there will also be an embarrassing period when the original ore turquoise begins to change color, but it does not completely change color. This is called a dish flower.

As long as you stick to the plate, part of the turquoise plate will disappear. Of course, some people don't like turquoise discoloration, which is also very simple. Regularly clean up the oil stain on the turquoise surface.

Rinse with clear water, and do not use any chemical lotion. The maintenance of turquoise worn or played with does not need to be done specially. If you don't play with turquoise, you should pay more attention.

Second, after the purchase of turquoise, let it watch, don't play with it:

This has to pay attention to some usual maintenance. Turquoise is a gem with water. Turquoise loses water, which is not conducive to its maintenance, so it needs to be replenished from time to time to maintain its beautiful and moving side.

Once every half month, soak turquoise in pure water to make it completely hydrophilic, about one day at a time, then put it in a sealed bag and store it in a cool place.

If it is stored in large quantities, it is suggested that it can be soaked in water all the time and put in the freezer to simulate the underground environment of turquoise, which is better for the storage and maintenance of turquoise.

Turquoise classification grade:

Turquoise is usually classified according to its origin, color, luster, texture, structure and structure, and many classifications extend to the quality grade of turquoise more or less, which has hierarchical significance.

First of all, through color

A. Blue turquoise: blue, opaque block, sometimes dark blue;

B. Parablue turquoise: light blue, opaque block;

C, turquoise: turquoise, opaque block;

D. Green turquoise: green, opaque block;

E, yellow-green turquoise: yellow-green, opaque block;

F. Emerald turquoise: Emerald, Yuhua some lights are transparent;

G. Light green turquoise: light green and opaque.

Second, by region

A, NiShahpour turquoise: produced in NiShahpour area on Ali Scrooge Mountain in northern Iran. China was called "Hui Electron" in ancient times, and Japan and other countries called it "Oriental Turquoise".

B. Sinai Turquoise: Located in the Sinai Peninsula, it is the oldest turquoise mine in the world.

C. American turquoise: produced in the southwestern States of the United States, especially Arizona.

D, Hubei turquoise: turquoise produced in China and northwest Hubei, called Jingzhou Stone or Xiangyang Dianzi in ancient times. Hubei turquoise is famous at home and abroad for its large output and excellent quality. Mainly distributed in Yunxian, Zhushan and Yunxi in northwest Hubei. The mine is located in the western end of Wudang Mountain and some areas south of Hanshui River.

There are Egyptian turquoise, Chilean turquoise, Australian turquoise and so on. However, some names of origin not only represent the origin, but also represent and indicate the quality grade of turquoise, so these names also have the meaning of quality grade.

Third, according to the structure

A. transparent turquoise: refers to transparent turquoise crystals. Very rare, only produced in Virginia, USA, the polished transparent gemstone weighs less than 1 carat;

B, massive turquoise: refers to dense massive turquoise with bright color, fine texture, toughness and smoothness, which is the main material of jade carving and quite common;

C. Tuberculous turquoise: refers to turquoise in spherical, ellipsoidal, grape-shaped, pillow-shaped and other shapes, and the size of nodules varies greatly;

D. Blue turquoise: also known as "lace turquoise", it refers to the turquoise that forms a spider's net pattern due to the existence of iron;

E, wire turquoise: refers to the turquoise with fine iron-black flowers on the surface;

F. Porcelain turquoise: refers to turquoise with sky blue, dense and tough texture, extremely bright fracture such as porcelain fracture after crushing, and good quality;

G vein turquoise: refers to vein turquoise produced in the fractured zone of surrounding rock;

H, variegated turquoise: refers to turquoise with speckled and star-shaped structure due to the presence of kaolinite, limonite and other substances, with poor quality;

First, the surface is loose: it refers to Wang An turquoise, with weak texture, granular fracture and low hardness, which can be scratched with nails. Some blocks are available;

J, bubble pine: refers to the turquoise softer than powder, inferior, and cannot be used as jade carving material. However, after artificial coloring and glue injection, this turquoise has become an optimized turquoise variety.

Fourth, international

Porcelain pine: it is the hardest turquoise with a hardness of 5.5~6. Because the fracture is shell-like, the luster and texture after polishing are very similar to porcelain, hence the name. Usually the color is pure sky blue, which is the top grade of turquoise.

Pine: the color varies from blue-green to bean green, and the hardness is 4.5~5.5, which is slightly lower than that of porcelain pine. This is medium quality turquoise.

Bubble pine: also known as face pine, light blue to moon white, hardness below 4.5, can be scored with a knife. Because this kind of turquoise is soft and loose, only the larger pieces have use value, and it is the lowest quality turquoise.

However, in today's increasingly scarce turquoise raw materials, manual treatment methods such as injection molding, wax injection and dyeing are often used to improve its quality and appearance, so it can also be "recycled".

Iron pine: a variety of turquoise, with black limonite veinlets distributed in a net shape, which makes blue or green turquoise appear black turtle back lines, net lines or veins, and is called iron pine.

The limonite veinlets above are called "iron wires". The iron wire is slender, firmly bonded and hard, and it blends with turquoise, making turquoise look like a natural pattern outlined with ink lines, which is beautiful and unique.

Turquoise with beautiful cobwebs can also be a good product. However, if the reticulate pattern is composed of clay veinlets, it is called mud line turquoise. Mud line turquoise is not cemented firmly, and its texture is soft, which is basically useless.
