Recently, the market is very popular, and there are many consumers chasing crazy, but the Chinese market is like this. What is good to sell this year, everyone will sell it, and some opportunists will be able to take it. There are many in the market. Different kinds of fakes, used to be fake jade, fake sheep fat jade, B goods, C goods, even B+C, still have it all the time, there are still many consumers who are not aware of the truth being cheated, being taken medicine, stupid Silly can't tell what is natural.
Now the clever Chinese people have used this method in the body, and a purple dragon crystal dyed into a comfortable body. A quartz stone dyed immediately became royal purple, and the purple sodalite is purple and transparent. The awful thing is the powder dyeing and soothing, and the carbon chrome-magnesium mine of the South African minerals, which is very similar to the ones that have been used for a few dollars, has risen a hundred times or more, soaking and soothing. Glue injection, so that those who are ugly or can not sell high prices become high-priced, good, water head.
Let's analyze what it is in the end. It is a kind of lithium iron silicate sodium silicate compound produced in manganese ore in South Africa, so the natural natural comfort is definitely stone, black. Point, semi-transparent, if it is transparent, it is very rare, very rare.
There are now five kinds of fraud laws:
I. Zilongjing dyeing
Is it familiar? Is it the one you bought? Is it enough that only a few hundred thousand is enough? Haha, tell you, this is still not dyed purple dragon crystal, dyed more like.
Very like it, cherry powder
Second, quartz stone dyeing
Is it royal purple in your hands?
Third, purple sodalite posing
This is the purple sodalite, is it similar to Xiaoshu? The surface of the purple sodalite has a granular structure.
This is the superficial superposition of the scales on the surface of Xiaosu Xiaosu, so it also caused a lot of tiny cracks on the surface or inside of the small Soviets after processing and polishing. So some people poured them on the surface. The more ethical is to provide transparency and clarity or to enhance the direct acidification and dyeing of the color. The acidified Susu will leave acidified spots, and the dyeing ones only look at the real thing with a magnifying glass and a flashlight to see if there is a silky structure inside.
Xiaosu is a very special stone light and two different colors appearing under the sun, blue-violet to purple-red, which you can look at.
The following are all purple sodalite:
Fourth, the powder is refreshing
I bought a bunch of Shuliang bracelets on a certain treasure. I cut the chain and chose a split. I didn't change the alcohol. I saw other people's suggestions. I used the fire to burn the original shape. After burning, the color is really powdery. .
Five, carbon chromium magnesium ore
Another stone carbon-chromium-magnesium mine produced in the South African mining area is similar in color to the small Su, but with different surface textures.
In addition to these five kinds of pure fakes, there are also inferior and low-grade fabrics that are soaked, dyed, and glued to make them transparent.
A gemstone is a stone. A natural stone must have its own characteristics. If you grasp this feature, you can definitely distinguish the authenticity. For example, if you are comfortable, his color must be in a block shape, and the color must be shallow. Different, uneven distribution, colored roots, remember not to be cheap.
“Su Ji Shi†is the name of an English translation. The English is sugilite, so some materials are also called “Su Ji Shiâ€, “Shu Qi†or “Su Ji Lai Shiâ€. The English dictionary is called sodium lithium marble. It is a sodium lithium silicate, often purple-purple red, and the refractive index is usually measured at 1.61, but sometimes a low value of 1.54 is detected due to its internal quartz impurities.
General quality Su Jishi
Because its color and refractive index are very similar to Charo stone (Purple Basilite), it is easy to think of it as Charo stone when it is first seen. Charo stone is also called "Zilongjing" in some foreign materials. The most obvious difference between it and Su Shishi is its fibrous and radial structure, and its color is very purple, while Suji is often purple. Red or purple.
Charlotte (Purple Silicate) (Zilongjing)
Su Ji Shi is a rare gemstone. It is known as the "Gem of South Africa". It is produced in the small rock of the Nishi syenite. The main component is silica, which contains various metal elements such as potassium, sodium, iron and lithium. It was discovered by a Japanese oil explorer, Mr. Kenichi Sugi, in 1944, so it was named after his name, but it was not until 1979 that South Africa discovered the gem-quality Su Ji stone due to the collapse of some Wessel manganese mines.
The appearance is a variety of opaque shades of purple and purple, or even deep to black, Royal Purple is the highest quality color, long-wearing can make the color of the brilliance more beautiful. The beautiful purple with different levels, combined with different shades, makes Su Jishi a mysterious and cool color. It is a very special gem.
The physical and chemical properties of Su Jishi
1. English name: sugilite
2. Mineral name: ferrosilicon nano-lithite
3. Chemical composition: (K, Na) (Na, Fe) 2 (Li, Fe) Si12O30
4. Crystal system and crystal habit: hexagonal crystal system, rare crystal, often semi-self-shaped granular aggregate
5. Color: red purple, blue purple, rare pink
6. Gloss and transparency: waxy luster to glass luster; translucent - opaque
7. Optical rotation: one-axis crystal, negative optical rotation
8. Refractive index and birefringence: The refractive index is 1.607-1.610 (+0.001, -0.002), and the spot refractive index is usually 1.61, but sometimes the low quality of 1.54 is detected due to the internal quartz impurities; birefringence Rate 0.003
9. Fluorescence: no to medium, short wave under blue
10. Absorption spectrum: There is a strong absorption band at 550 nm, and there are absorption lines at 411 nm, 419 nm, 437 nm, and 445 nm. This absorption spectrum is the result of the interaction of manganese and iron.
11. Cleavage and fracture: no cleavage; uneven fracture
12. Mohs hardness: 5.5-6.5
13. Density: 2.74 (+0.05) g/cm3
14. Magnification check: Deep purple body color is the main identification feature
舒石徕石Sugilite[è‹çºªçŸ³]
The most high-grade Su Ji Shi and high-grade citrine are quite price-priced, even higher. Therefore, the name of Su Ji Shi, the color is poor, and even Su Ji Shi, which has serious mineral shortages, can become a hot commodity in the market.
Su Ji Shi's three major appearances, one is dark purple near black, one is metallic, and the other is purple.
A fake Su Shi stone characterized by metallic color has appeared on the Internet for some time. The seller also lied to Su Shishi, a special product at a high price. This kind of fake Su Jishi, I have not seen the real thing, only seen photos on the Internet. A wholesaler has confirmed this "Golden Shu Shi", not really Su Ji Shi.
Another fake Su Shi stone featuring purple, which is now in the wholesale market, may appear on the Internet in the past two days. According to my personal experience over the past year or so, I have seen almost all the colors of Su Jishi. The great feature of Su Ji Shi is its luster. No matter what color of Su Ji Shi, its luster has a metallic luster texture. I can understand what I mean by looking at the light from different angles.
The picture below is the same. The two Su Ji Shi on the right contain almost all the common colors of Su Shishi. The two on the left are the new fake Su Ji Shi.
