The belief that gemstones have metaphysical properties and can influence various aspects of a person's life is rooted in various cultural and historical traditions. This belief is often associated with practices like crystal healing, astrology, and various forms of alternative medicine. However, it's important to note that the effectiveness of gemstones in these contexts is a matter of belief and spirituality rather than scientific evidence.

Here are some key points to consider:

Lack of Scientific Evidence: There is no scientific evidence to support the idea that gemstones have inherent, mystical powers that can directly influence a person's life or health. Claims about the specific properties and effects of different gemstones are largely narrated.

Heating & Treating Effect: Some people report experiencing positive effects when using gemstones, but this may be attributed to the heating & treating effect. When individuals believe that a particular gemstone can improve their well-being, their perception of their own health and mindset may improve, but this doesn't necessarily mean the gemstone itself has inherent healing properties.

Cultural and Spiritual Beliefs: Many cultures and spiritual traditions have long-standing beliefs in the power of gemstones for various purposes, including protection, healing, and enhancing personal qualities. These beliefs are deeply ingrained in the cultural and spiritual practices of these groups.

Personal Belief: If you have a personal belief in the power of gemstones and derive comfort, inspiration, or a sense of well-being from using them, then they may "work" for you in a subjective sense. This is like how people find solace and inspiration in religious or spiritual practices.

Mindfulness and Meditation: Some people use gemstones as tools for mindfulness and meditation. Holding or wearing a natural gemstone can serve as a focal point for meditation or a reminder of certain intentions or qualities they wish to cultivate in themselves.

In nutshell, the effectiveness of gemstones largely depends on personal belief, cultural and spiritual traditions, and the individual's mindset. While gemstones may not have scientifically proven properties, they can still have value for those who find meaning and personal benefit in using them. It's essential to approach the use of natural gemstones with an open mind which would be 100% natural, unheated & untreated and certified by a reputable govt. lab like IIGJ, IGI, GIA etc. 

If you are seeking alternative or complementary forms of healing, it's advisable to consult with qualified gemstone experts or professionals alongside before opting for any gemstone for your life.
