Crystal is produced in water environment and is a kind of water-based gem.
Fundamentally speaking, the correspondence between gems and five elements is not understandable by simple thinking, or it is hard to say how significant it is to divide gems by five elements and how much it affects people, and all gems actually belong to gold. Perhaps in the final analysis, it is just a word game, which has little influence on people.
The formation of crystals must have water, which is water-based; Crystals of different colors can correspond to five elements through five colors.
Do you know what volcanic rocks are called? It's called basalt Basalt in China traditional culture means that the north belongs to water, so it makes sense to classify obsidian as water-based according to its color. You can understand it this way: Obsidian and basaltic are the substances left by the fiery components released from volcanic protoplasm, that is to say, they should not be fire, but water. But this explanation is for reference only, because I can't say what it is. Even if it is really waterborne or fireproof, how much impact will it have on people?
In ancient times, matter was divided into five elements, which generally depended on factors such as color, orientation, sound and taste. My feeling is not too complicated. Perhaps the five elements are an elastic model, allowing different standards, so the same substance may be different lines in different categories, and there are both components belonging to this line and those belonging to that line in the same thing. It's best not to dwell on these, even if there are "masters" and different masters, maybe the answers are different. Besides, can you really meet such a master who can scientifically set standards in reality?
The most meaningful difference between gems is neither color nor cause, but composition. For example, different crystals, the only difference is the different elements. Red crystal is because it contains red iron oxide, and ruby is because it contains chromium. I don't know much about chromium And many soils or water bodies containing trivalent iron are obviously flammable in similar things because of their strong oxidation and acidity, so
It makes sense to classify red crystals as fire crystals.
It is also very important: I feel that your constellation is not too short of fire. Although there is no fire, you are full of wood and gold, and fire has its mother. If you still wear gems according to the lack of fire, you can bring rubies such as agate, carnelian, garnet and ruby. If you must wear a crystal, it should be a red crystal.
