Amethyst Cave is a common feng shui ornament, and we can often see them at home, companies, hotels and other places. There are also many people who want to know how this amethyst cave was formed. Where were they born? Today, let's follow the footsteps of Yicheng to have a look.

The most important amethyst deposits in the world are distributed in igneous basalt in Uruguay and Brazil respectively. This igneous rock is widely distributed in Latin America, with an area of about 1 200,000 km2 and a predicted volume of about 800,000 km2. Such a huge number, some people will say, is it all amethyst over there? In fact, through in-situ observation, amethyst is limited to a specific area and a specific basalt lava flow.

Amethyst cave is formed by the slow infiltration of groundwater containing silicon dioxide from the edge of agate cave, and after a long period of condensation and crystallization. The most primitive type of amethyst cave is spherical crude ore, which has become a common amethyst cave on the market after being cut in half. Generally, the amethyst cave we see has three layers, the innermost layer is purple grains, the middle layer is agate, and the outermost layer is a cement protective layer added by workers. There are also good crystal holes polished outside. This kind of polished crystal hole usually requires a thick agate wall outside, so there are few polished crystal holes and the price is expensive.

When high-temperature silicon-containing hydrothermal solution is poured into the crystal cave, if the crystal cave itself is cold and the temperature is quite different from that of the hydrothermal solution, the supersaturation of mineral liquid at the edge of the crystal cave is very large at first, and it is easy to form many tiny "crystal nuclei" in a short time and grow steadily and continuously. As you can imagine, so many small crystal nuclei grow along the cave wall at the same time, and they will soon contact each other and cannot continue to grow. Therefore, the earliest agate-aphanitic time-dependent aggregate is often formed at the edge of the crystal cave.

When many small amethysts grow densely together, amethyst flowers will form, which, like amethyst caves, have the function of blocking evil spirits and avoiding evil spirits in feng shui. Amethyst caves should be placed away from direct sunlight. Too much sun exposure will lead to the fading of amethyst and magnetic field.

? The growth of amethyst cave is not easy, and every amethyst cave placed beside you has come to you through hardships!
