"Wood to Stone" sounds like a stone made of wood, but in reality, it has nothing to do with wood. So why is it called that? Is there really a stone made of wood?

What is wood-to-stone
The scientific name of wood-metamorphic stone is silicified fossil wool, which is a quartzite jade formed by the acidic hydrothermal silicification of horn amphibolite blue asbestos. Silica fossil wool is often a fibrous structure of the plate-like block, opaque, the polishing surface is silky luster, the curved surface will have a cat's eye effect, when the light band is perpendicular to the direction of the asbestos filament, it has active light. Its largest production deposit is the Transtual Deposit in South Africa, which is also produced in Brazil and the mainland of Henan and other places.

Silicon fossil wool has nothing to do with wood during the formation process, but its texture and color look very much like wood, so it is commonly known as wood stone. But compared to the name "wood stone", its mineral name, that is, "tiger eye stone", is more well known.

The shade of color is affected by the light band, the light band is light, and the two ends of the light band without the light band are dark.

Although wood-to-wood has nothing to do with wood, there are also stones that are actually transformed from wood, such as the silicified wood that will be introduced next.
Real wood fossils – silicified wood
Silicified wood is a fossil tree that is replaced by silica in groundwater after trees were rapidly buried in the ground millions of years or earlier. It retains the wood structure and texture of the trees, but the composition itself is no longer wood. In addition to being accounted for by silica, the xylem of plants can also be explained by calcite, dolomite, apatite, and even some limonite, pyrite, etc., which are collectively referred to as petrified wood.

Silicified wood has many production sites at home and abroad, and is an important fossil ornamental stone species. Because of its delicate texture, hardness, rich color and clear lines, it is often made into mountain stone bonsai, decorative crafts and jewelry.

Most of the silicified wood on the market is processed, and only very rare and well-shaped ones are sold as rough. The processing method is sanding and polishing and sandblasting processing, which removes the bark and impurities on the surface and exposes the jade layer in it. In this way, the original natural shape of the wood fossil can be maintained, and the exquisite jade structure inside it can be revealed.

At present, the most common use of silicified wood in decoration is to be made into a variety of ornaments, whether it is directly placed in the rough, or after exquisite polishing and carving, it is very beautiful.

But it is still used in jewelry very little, mostly made of beads and bracelets.

In contrast, wood-to-stone is much more widely used in jewelry. Although the most common in China is also a bead string, its unique texture makes it appear in high-end jewelry.
