According to various scholars, although are scientifically and medically unproven and therefore only speculation, untreated crystals and gemstones are said to have protective properties that are timelessly effective and have no side effects.

Some people even report miraculous healing effects, noticing a positive influence on the mental and spiritual plane where most illnesses have their origin. This mental and spiritual level is inaccessible to almost all other medications or remedies.
Through their radiation, the energetic gemstones, crystals, quartz crystals, etc. are said to penetrate deep into the individual body cells and contribute to regeneration, strengthening and protection – thus improving our well-being, psyche and quality of life.
The energetic gemstones and crystals are intended to activate the cosmic and divine powers of our soul, without any side effects.

For clarification:
The minerals, crystals, gemstones, quartz crystals, etc. referred to by many as so-called “healing stones” are not medical products. There is no scientific or medical evidence of their effect on the body or influence on illnesses or the consequences of accidents.
Nevertheless, there are people who report positive effects and successes when using so-called “healing stones”, although these may be entirely subjective sensations in the sense of a placebo effect.

Those who believe in the healing powers of energetic gemstones, crystals, quartz crystals etc. usually justify this as follows, for example Hildegard von Bingen:

I chose to work with energetic minerals, gemstones, crystals and quartz crystals because they are said to have a positive effect on certain people and can serve as a type of “vehicle” to support the healing process – even if it’s just a type of placebo effect.

For several years now, I have been making individual energetic jewellery myself. My jewellery is characterized by the fact that it is not only beautiful, but also energetically optimized and attuned to the wearer and their current inner processes.
