Help identify the authenticity, how much it is, what kind of obsidian

Specifically, you can send ** to see.

This ** effect, it is difficult to judge the type of material.

The obsidian component is natural glass, the market value is not high, and there are not many counterfeits. Ordinary obsidian bracelets, in most areas, are around tens of yuan to 100 yuan. If the quality color is good, it is a few hundred yuan less.

I'll tell you the truth, I have a real obsidian bracelet. But it's really not worth much! He is not worth much. Because his amount is too large.

Obsidian is an ordinary piece of jewelry, unlike Hetian jade and jadeite, which is not a precious gemstone and is not worth much. You can buy it for dozens to more than a hundred. But it still looks like a good accessory.

Hello, subject, pure black obsidian is impossible to judge with the naked eye, because the same also has black agate, but the large production of obsidian can only be said to be less fake, but it is not nothing.

Natural obsidian ** at 100 yuan-300 yuan, mainly depending on the obsidian specifications, model size, see how much it is worth. Synthetic obsidian bracelet** is around 15 yuan.

The cost of obsidian is not high, but his meaning is good, obsidian bracelets and pendants are generally around 100 to 200, and obsidian is generally around 200 to 400.

Obsidian is not counterfeited under normal circumstances, after all, the cost of the real ** is lower than that of the fake, and there is no need.

I guess it's true. Obsidian is not a scarce stone. Not very valuable.

It doesn't matter if it's true or not, obsidian is natural glass, not worth a few dollars, except for a few rare colors of obsidian will be faked, general obsidian jewelry has no need to counterfeit, counterfeiting also requires cost.

Obsidian, is an acidic vitreous volcanic rock with a composition comparable to granite. Except for a small amount of speckle crystals and rudimentary crystals, almost all of them are composed of vitreous. It is usually black, but brown, gray, and a small amount of red, blue, and green materials are also visible.

The color may be monochrome, striped, or speckled. Dense massive, sometimes with stone bubble structures. The glass has a distinct luster and a shell-like fracture.

The water content is less (<2%), which can be distinguished from perlite and turpentine. It is commonly found in areas of acidic volcanic rocks. Together with pine, perlite, and pumice, it is collectively referred to as acid volcanic glass rock.

Obsidian can be used as a raw material for decorations and crafts.

This ** looks like it should be, but ** will not be very high, because this stone is more common, so the value will not be so high.

Identifying the authenticity of obsidian can be distinguished from three aspects: technology, whether there are rainbow eyes, whether it is yellow light, and the real obsidian has some slight damage on the surface, and it is not very smooth, which is the easiest way to identify.

1. Identification from the process.

Because the glass products are poured with a mold, they do not need to be polished and polished, so the surface of the fake obsidian is particularly smooth and has the characteristics of reflective glass surface. After the genuine obsidian is carved, it still needs to be polished, but no matter how good the polishing is, there will be sand holes or slight damage, and it will not form a very smooth glass surface.

2. Observe if there are rainbow eyes.

One of the most important features of obsidian is the rainbow eye, which is known as rainbow eye when illuminated with strong light. Obsidian carvings must be viewed closely on the smooth back, and in the case of obsidian bead bracelets, rainbow eyes are easy to see in sunlight or bright light.

3. Whether the strong light transmission is yellow light.

We can turn on the mobile phone flashlight, put the back of the obsidian carving on the mobile phone flashlight, and on the front of the obsidian carving, we can see the yellow aperture through, if it is a fake obsidian, it will generally reveal the blue aperture. If the obsidian carving is too thick, the strong light will not shine through, and it can be identified in combination with other methods.

1. Ordinary obsidian without rainbow eyes, that is, the beads are still black under strong light, and there is no other reflection, if it is a pendant through the light, the light is yellowish and green. This type of obsidian is the most produced, but the market value is the lowest, and it is generally used to make large carvings.

There are few such fakes on the market, but there are also unscrupulous merchants who use stained glass as (the most common is this kind of small Pixiu pendant, retail ** is a few to a dozen pieces) and inferior black stone (generally a large carved piece, which is characterized by a lot of gray and white spots can be seen in the light), these two types of fakes are very difficult to distinguish for non-connoisseurs, and you can use strong light to see whether it is yellowish and dark green.

2. Rainbow eye (light) obsidian, that is, looking at the strong light, or looking in the sun, or looking under the flashlight of the mobile phone, slowly shaking, you can see the reflection of green, purple and yellow, among which the rare quality surface will appear ghost fairy red eye obsidian surface light red, ghost fairy blue eye obsidian surface is light blue, ghost fairy red and blue eye obsidian surface is red and blue and other colors, the quality is very rare. A large number of rough stones can only be selected in small quantities of this quality, so it is even more rare.

Obsidian in circulation today refers to obsidian, a natural glass that can be used as a gemstone. Obsidian ranges from transparent to opaque, from black to brown, red, yellow, and gray, to very light greenish or bluish, most commonly opaque to translucent black to slightly brownish dark red. There are several varieties of obsidian, such as banded obsidian, obsidian and chrysanthemum obsidian.

The composition of this natural glass is roughly equivalent to that of granite, containing 60%-75% silica, as well as some alumina, alkali metals and iron. Amorphous, glass luster, hardness 5-Mohs hardness), the toughness is quite good, the fracture is shell-like, density, refractive rate. Mean body, no birefringence and no pleochroism.

Obsidian is widely distributed all over the world. Some of the more famous producing regions are Mexico, New Zealand, Iceland, Hungary, Greece and the United States.

Naturally occurring obsidian varies in size from small globular to mat-like mats up to hundreds of meters in size. This rock is formed by the rapid cooling of magma when it encounters lakes or other bodies of water under low pressure on the surface.

Obsidian opacity is normal, and by color eyes you mean that some obsidian varieties contain microcavities with needles and bubbles extending inside, and their reflection of light can create a silvery white glow. This feature can be artificially imitated. Also, you take obsidian to scratch the glass, obsidian itself is natural glass, so the hardness is the same as the hardness of artificial glass, and it is normal to have obvious scratches (ps:

No scratches are abnormal! Finally, how to distinguish: obsidian usually contains bubbles and streamlines, and the bubble walls are thinner than the bubble walls in glass, with these intuitive characteristics and density, the small refractive index can be distinguished from other gemstones (other imitation substances) that are confused with it!

I tell you the truth, people who do not have long-term appraisal experience are unrecognizable in the naked eye, although I have learned appraisal but there is no professional appraisal equipment can not be identified, you have to figure it out to go to a professional institution to do the appraisal!

Obsidian itself is a very low-grade gemstone There is no need to make fake ones There are scars Because obsidian belongs to volcanic glass Glass also belongs to glass in layman's terms My string is not transparent The color is too dark It is normal Rainbow eyes will appear in the strong sunlight This is true Don't worry, yours should be real.

Obsidian is a low-to-medium gemstone, even the most expensive of the brand is only a few hundred, and it is generally transparent. If yours are completely impermeable, it's either something that contains carbon and something is imitated, or it's black agate, in fact, the price of agate and obsidian is about the same, or it's a rare kind of obsidian, which is super expensive. There are many kinds of color eyes, and they are generally not fake, they are cheap, so there is no need to spend this cost.
