The magnetic field generated by crystal has a certain role in refreshing and stabilizing emotions. Crystal can concentrate the energy of the human body. Therefore, this method is also called “crystal therapy” by American researchers. In addition, the crystal contains a large number of trace elements, such as manganese, iron, steel, titanium, etc., which are beneficial to the human body. In addition, during its formation, it will be exposed to underground radiation and retain a small part of the radioactive elements. These radioactive elements contain very small amounts, so they will not cause too much harm to the body. On the contrary, after long-term research, it is found that she will have the role of radiotherapy.
How to distinguish the quality of crystal?
First, there is cotton wadding. In addition to a few crystals with little cotton wadding, natural crystals have more or less cotton wadding. The more cotton wadding, the lower the general quality.
Second, look at impurities, because natural crystals are all products of nature. After thousands of years of accumulation, they will be more or less doped with some minerals and impurities due to earthquakes and other reasons, and gradually formed on the surface or included in the interior. The more impurities, the more naturally affect the quality.
Third, ice cracks. Since natural crystals are formed in the natural environment over time, they will naturally have some broken lines under the influence of earthquake movement, debris flow and other external forces, which is also a major feature of natural crystals.

The hardness of the real necklace is 7.00 and the refractive index is 1.54, while the fake necklace is only 5.2~6.10 and the refractive index is less than 1.00. The natural crystal is hard, so you can use crushed stone to gently scratch on the jewelry without leaving traces. If there are streaks left, it is a fake crystal ornament.
From the perspective of purity, during the formation of crystal, it is often affected by the environment and always contains some impurities, some of which have different degrees of flaws and colors.
