1. Common crystal types and their scientific properties and "efficacy" in popular culture
| Crystal name | Main Component/Mineralogical Classification | Color Features | Scientific Properties/Uses | "Efficacy" in Popular Culture (Metaphysical Perspective) | |
| quartz (quartz family) | silicon dioxide (SiO ²) | colorless transparent | Piezoelectric (force generates current, used in clocks, electronic components), optical instruments. Pure quartz is an excellent electrical insulator. | Considered the most powerful energy amplifier and purifier, it can boost all energy. | |
| amethyst | quartz variant (containing trace elements such as iron) | light purple to dark purple | Same as quartz. | Calm the nerves, relieve stress, improve spirituality, help sleep, prevent villains. | |
| citrine | quartz variant (containing trace elements such as iron) | pale yellow, golden, orange | Same as quartz. | Attract wealth, enhance confidence, bring joy and vitality, and promote creativity. | |

- Culture and Symbolism: Many crystals derive their benefits from long-term cultural accumulation and symbolism (e.g. garnet symbolizes passion and loyalty, powder crystal symbolizes love).
- Need "purification" and "charging"? In the energy healing perspective, crystals are believed to absorb negative energy or weaken energy, requiring regular purification (e.g. with running water, moonlight, smoke, sound, burying soil, etc.) and recharging (sun, moonlight, placing in a crystal cave, etc.). This is more of a ritual to keep crystals clean and maintain personal psychological connection.
III. How to choose and use crystals
Summary
Crystals are beautiful minerals endowed to us by the earth and have unique scientific and aesthetic value. It is objective and interesting to understand their mineralogical properties and applications in science and technology. For the widely circulated “ efficacy ” , please understand it as a cultural phenomenon, psychological tool or personal belief practice. To approach crystals with an appreciative, curious, and rational attitude, respecting science and different ways of spiritual exploration, is the correct way to enjoy the beauty of crystals.
