Black onyx and obsidian are the same black stone treatment stones, similar in appearance and similar in price. Let us know what the difference between the two gems is. One of the differences between black agate and obsidian: color The texture of black onyx has no obvious elliptical ring shape, but only a small part of the natural agate has a crystalline state, such as strips, spots, and dense blocks. One is on the black agate. You will find that some of the beads are all black. There is no other color or halo on the surface. A layer is transparent or translucent or white. This is the best way to identify agate. method. Obsidian is a natural glass with a black background, but with a monochromatic or colored stripe or pupil-like halo on the base. This is the most obvious difference between the two. They are all opaque. You can carefully observe the surface of the bead under strong light. There is no halo, there is obsidian, no black agate. The difference between black agate and obsidian: formation Agate is obtained by solidification of silica colloid. The main component of agate is Sio2 (silica). When the texture is very pure, it is gray. If it contains various pigment ions, it will appear red, black, blue and green. It has a deep or shallow belt structure. Obsidian is a component of volcanic magma that cools down, and internal bubbles or crystals produce a "snowflake" effect or a rainbow color that is seen as a flash. If you look at it with a microscope, you will find that the surface of obsidian is actually pitted and has many small holes. Black agate does not have these. On the gloss, you will see that the black onyx is silvery white when it is illuminated by natural light, and the reflection will be like a mirror. If your eyesight is good, you will look at the black onyx and you will see that the black onyx looks like you are in the mirror. Obsidian can't do this because the obsidian is not flat and polished well without the effect of black onyx.
