Trapiche (Trapiche) refers to a machine used to press sugarcane to obtain the raw liquid that is the source of sugar. When the six-spoked gear-like shape used in that machine is found in minerals, it is called Trapiche [Mineral Name]. It appears in ruby, sapphire, emerald, amethyst, smoky quartz, etc. There may be others. The first three types, up to emerald, form a gear shape as if dividing the room, which is closely related to the appearance of a six-rayed star (explanation omitted here). Amethyst and smoky quartz are related to the hexagonal crystal structure, where the six faces of the pyramid alternate between purple, colorless, purple, and colorless. Perhaps the former type is what is originally called trapiche, and it is somewhat skeptical to call the latter type trapiche, but it probably started to be called that because it looks like a gear. This time, I used the name in accordance with the industry trend. Amethyst is colored purple due to an error called a lattice defect in quartz, and iron ions are included as impurities. The concentration of iron ions causes color unevenness in the shades of purple. If mineral water that does not contain iron ions is supplied during the growth process, colorless quartz parts will also be mixed in, resulting in a strong contrast. I previously purchased sliced loose stones, but this is the first time I've received a pendant type. It's not something you can easily find, so please consider this opportunity (^o^).
