Obsidian is a kind of stone, different from crystal. Although it is also the molecular structure of silicon dioxide, it is completely different. From the shape point of view, obsidian is generally not a right circle, but is generally processed to show the shape that everyone sees.

Of course, as spar, the efficacy of these two stones is still hard to ignore. They not only have the effect of expelling wind and evil spirits, but also play a very obvious role in health preservation.

Which is better, black agate or obsidian? These two points give you the answer. One of the differences between black agate and obsidian is color.

The texture of black agate has no obvious oval ring shape, but only a few natural agates are crystalline, such as strips, dots and dense blocks. One of the manifestations on black agate is that you will find that some beads are all black in one aspect, with no other colors or halos on the surface, and some are transparent or translucent or white. This is the best way to identify agate.

Obsidian is a kind of natural glass, the background color is all black, but there are monochromatic or colored stripes or holes on the base. This is the most obvious difference between the two. Are opaque. You can carefully observe the surface of beads under strong light, whether there are halos, obsidian and black agate.

The second difference between black agate and obsidian is the stratum

Agate is solidified by silica colloid. The main component of agate is Sio2 _ 2 (silicon dioxide), which is gray when it is pure, red, black, blue and green when it contains various pigment ions, and has a deep or shallow ring structure.

Obsidian is cooled by some components of volcanic magma, and bubbles or crystals inside it produce "snowflake" effect or are regarded as flashing rainbow color. If you look at it with a microscope, you will find that the surface of obsidian is actually pitted with many small holes. And black agate doesn't have these. In terms of luster, you will see that black agate will appear silvery white under natural light, and the reflected effect is the same as that of a mirror. If you have good eyesight, if you look at the black agate, you will see that the black agate has your appearance, just like looking in the mirror. Obsidian can't do this, because obsidian is uneven, and even the best polishing will not have the effect of black agate.

The third difference between black agate and obsidian is the weight.

At the same time, if two black agate bracelets are as big as obsidian bracelets, black agate bracelets are obviously heavier than obsidian bracelets. Obsidian is light because it has many small holes.

The difference between obsidian and black agate and black tourmaline

1, the difference between obsidian, black agate and black tourmaline in appearance:

Obsidian is a kind of natural glass and an amorphous gem. It is a silica semi-colloidal ore body, usually black in color. Obsidian, as a gem, generally has iridescence and eye effect, so its color is changeable, not black. The surface is metallic luster, and the brightness is relatively low;

Black agate belongs to chalcedony, with thick and opaque color, very smooth and bright appearance, no colored light and no development line at all, which can be described as shiny and shiny. Black agate looks brighter than black tourmaline;

Black tourmaline is actually a kind of black tourmaline rich in iron. Natural black tourmaline has many variegated colors. Under strong light, there will be development lines on the surface. Under normal circumstances, it is normal that there will be small defects like pits on the surface of black tourmaline. Black tourmaline is dark in color and not translucent. Its surface luster is a kind of glass luster, and its brightness is not as bright as agate.

2. See the difference between obsidian, black agate and black tourmaline from the specific gravity;

The specific gravity of obsidian is 2339-2527, that of black agate is 260, and that of black tourmaline is 298-320. Compared with the jewelry of the same specification, black tourmaline is the heaviest and obsidian is the lightest.

3. Distinguish Obsidian, Black Agate and Black Tourmaline with glass strokes;

These three substances belong to obsidian, and their hardness is only 5-5, 5, so they are not easy to scratch the glass, but also easy to hurt each other, while the hardness of black agate is 7, and the hardness of black tourmaline is 7, 5-8, which are easy to scratch the glass. Among them, the black tourmaline has the highest hardness, which is easy to scratch the glass and is intact.

It takes a lot of practice and experience to distinguish obsidian, black agate and black tourmaline.
