Quartz Crystals are characterized by being able to store, refract and amplify energy.
Some people call all crystals "stones" and that is not the case. A stone is a stone and a quartz crystal is a quartz crystal, things as they are. We have to make a big difference between glass, quartz crystals (wrongly called semi-precious "stones") and common stones of a more opaque and non-translucent character.
Some people also do not believe in the properties of quartz crystals that are scientifically proven today. Which leads us to the conclusion that what some call skepticism is just ignorance.
Cell phones, computers, spaceships and a myriad of devices have quartz crystals inside. Without these crystals and their characteristics it would be impossible to function.
Quartz crystals could well be used to heal and heal diseases since with crystals it is precisely possible to undo, direct and metabolize Energies and the Human Being is Energy. It is clear that crystals are cheaper than drugs and their use would not be profitable compared to the large pharmaceutical multinationals.
It is precisely those scientifically proven properties of quartz crystals that an experienced therapist uses to balance the human energy body, that is, its Soul where the root of all physical manifestations of diseases and dysfunctions is usually found.
Say also that what modern science has now shown regarding the properties of quartz crystals has been used since the dawn of mankind in all known cultures.
In any case, for people who still do not believe in the healing properties of quartz crystals, inform them that every day humans ingest a quantity of crystals such as sugar, salt, vitamin C, etc.
