Wood to stone is opal, tiger eye stone, opal, also known as "cat eye", an amorphous silica, contains a clear color discoloration, stone has natural wood halo, also very similar to felines Named after the eyes of cats and tigers, it is often used as a gemstone.
Both the tiger eye stone and the eagle eye stone are variants of wood stone. The tiger's eye stone is named after the brown-yellow and yellow-brown wood stone, which is honed into a curved gemstone. In addition to yellow fiber, tiger eye stone has more blue and red fibers, which are blue, brown and red. The whole is mainly yellow. The quartz fiber of the tiger's eye is shorter than the wood, and the direction is irregular, and it is arranged in any direction like the marking. Under normal circumstances, the block of the tiger's eye stone is larger than the wood, and the stone is mostly fine veins. The eagle eye stone is a gray-blue or dark gray-blue wood stone that is honed into a curved gemstone. It has the cat's eye effect similar to the "eagle eye". The eagle-eye stone is that the original blue asbestos was not replaced by quartz, maintaining the gray-blue color of the original blue asbestos.
Silicified products of asbestos, alkaline amphibole (sodium amphibole, magnesium sodium amphibole, magnesium sodium iron amphibole, manganese amphibole) asbestos, also known as silicified asbestos.
In a suitable geological environment (chemical, physical), the Si02 colloidal solution is continuously and gradually crystallized, and the asbestos (serpentine asbestos) and blue asbestos (blue asbestos are the trade names of basic amphibole asbestos) are formed into silicidation. Asbestos, silicified serpentine, and alkaline hornblenster asbestos are also known as wood tones when they reach the jade index.
The wood-reduced stone is mainly composed of his granular aggregate quartz, which has unequal grain granitic crystal structure. The fibrous structure of serpentine and alkaline hornblende remains in the quartz aggregate due to the difference in the strength of the metasomatism. And residual crystals, when the fibers are arranged in parallel, the arc-shaped ring face can be honed to produce a cat's eye effect, and when the fibers are disorderly distributed, other crafts can be honed by the situation.
