Description of Jade

Mineral class: phyllosilicates. Chemical formula: NaAl[Si2O6] + Ca, Fe, Mg, Mn

Jade is an ornamental stone and not strictly a mineral, but rather a collection of particular silicate minerals (jadeite and nephrite) distributed in a structure made of very fine granules and interwoven fibers.

The color is rarely uniform: on a white or off-white background, subtle shades of pink, lavender, or purple blend together, or more often emerald green or light green due to the presence of chromium.

Today, other minerals are sold under the name of jade, such as serpentine, which not only has the same appearance but is also extracted from the same deposits as jadeite and nephrite, although it is more malleable and less resistant.

Element

Water: the water element concerns the sphere of emotions and femininity (love, healing, compassion, reconciliation, intuition).

Chakra associated with Jade

Second chakra Svadhishthana ("Sacral") and fourth chakra Anahata ("Heart")

Mythology

The name "jade" comes from the Spanish pedra de ijada, meaning "stone of the flanks," given its traditional beneficial power over the lower back and kidneys, and dates back to the time of the Spanish conquest of Central America, where this stone was highly appreciated and finely worked.

In ancient China, it was a sacred stone used to make urns because it was believed to have the power to prevent corrosion and ward off evil spirits. In traditional Chinese literature, gold and jade are often mentioned together and are considered symbols of wealth.

Even today, the price of good-quality jade is worth no less than a piece of gold of the same weight.Confucius (551-479 BC) states that jade possesses eleven virtues, including benevolence (it is smooth and lustrous to the touch), fidelity (it never irritates the skin), education, and sincerity (a flaw in jade is never hidden). Confucian culture also taught that a man should define his manners and conduct in accordance with the virtues of jade.

Shungite has the ability to absorb particles (pollutants) from the environment and has antibacterial properties.

The stone is used for protection against electrosmog from computer screens.

Furthermore, it has been used since the 18th century for medical treatments. Peter the Great founded the first Russian spa in Karelia and used the purifying properties of Shungite water there.

He also used it to supply the Russian army with purified water.

Shungite: uses and benefits

Since time immemorial, Shungite has been considered a stone capable of adapting to the needs of the living organism it comes into contact with. It is a rare rock that has been recognized for many therapeutic virtues. Among these, one of the most important is undoubtedly its ability to act as a shield against electromagnetic waves harmful to the human body.

Origin and composition of Shungite

Characterized by a color ranging from deep, matte black to metallic gray, Shungite is an amorphous mineral whose origins are lost in the mists of time. Its molecular composition is also rare: the stone is made up of 98% carbon. There is another element that makes it particularly unusual and precious; its internal structure is formed by fullerenes. These atypical molecules bond together to form an unusual hollow cage-like structure. Shungite is the only known mineral that contains them; it is therefore an atypical, almost mysterious rock. This aura of uniqueness is also reinforced by another fact concerning its extraction.

The only Shungite deposit is located in Russia, in Zazhoginsky, near the village of Shunga, where it was discovered and from which it takes its name. Even the theories regarding the origin of Shungite fall within that aura of mystery surrounding it. On the one hand, some believe that, given its organic carbon composition, it derives from planktonic deposits dating back two billion years, while others claim that the stone comes from a giant meteorite that crashed into Earth.

What are its properties?

• Shungite has countless properties:
• It has antibacterial and antiviral properties
• It counters electromagnetism, radiation, and electrosmog
• It helps with sleep and rest
• It boosts immune defenses
• It combats headaches
• It has anti-inflammatory properties
• It has antioxidant properties
• It has antihistamine effects

Whatever its origin, what is known for certain is that Shungite is a mineral with numerous properties and benefits. Peter the Great, the first Emperor of Russia, was so convinced that the stone possessed numerous healing and antibacterial properties that he gave it to all his soldiers. The intention was to use it during military campaigns both to treat wounds and to purify water.

And it is precisely this close connection between this stone and water that is fundamental to understanding its extraordinary virtues. According to a study published in 2018 by the eminent scientific journal ScienceDirect, Shungite, thanks to the high amount of carbon present in it, not only purifies water by removing viruses and bacteria, but can also eliminate radioactive compounds present in it. Its action therefore allows harmful substances to be expelled while enriching it with oligominerals and beneficial substances.

Daily cleansing with Shungite water, obtained simply by leaving the stone to infuse overnight in a bowl or bottle, gives skin an elastic, smooth appearance and gives hair exceptional shine. A gauze soaked in Shungite water helps treat burns and minor bruises, while a bath of just 15 minutes helps reduce stress naturally and harmonize energies.

Thanks to its anti-inflammatory and antioxidant properties, it proves to be an excellent ally in combating respiratory and gastric problems and alleviating chronic fatigue. Shungite helps the body sleep better and recover lost energy.

Some holistic practitioners recommend always carrying Shungite during flu epidemics because this stone stimulates immune defenses.

Its properties make it an excellent fertilizer, capable of increasing plants' resistance to diseases and pest attacks by 30/40%.

We have saved one of the most important and renowned properties of this stone for last: the ability to neutralize any type of radiation and electromagnetic wave. In a world immersed in continuous physical and mental stimulation caused by devices such as Wi-Fi, mobile phones, televisions, and PCs, Shungite becomes an effective shield capable of canceling out the negative effects of electrosmog.

Shungite for electromagnetic waves

Can a simple antenna, radio alarm clock, or phone pose a threat to human well-being?

Technology is making giant leaps, simplifying many aspects of everyday life. However, this new world, in which hyper-connectivity becomes essential, exposes humans to a large number of harmful radiations coming from our PCs and mobile phones, but also from hidden and unsuspected sources such as the wireless network that invisibly surrounds our homes.

The transmission, conversion, and use of electrical energy generate electromagnetic waves that can be high or low frequency. Their impact on living organisms is not without side effects, especially on the most sensitive people.

Electrosmog can impair cognitive abilities, weaken the immune system, and make it more vulnerable to neurodegenerative diseases; it is a form of pollution that drains energy and predisposes people to insomnia, anxiety, depression, and frequent headaches. Years of experience have shown how electromagnetic waves have a marked influence on the water we drink, the places we frequent and live, and the air we breathe.

Scientists, including the Russian Kaznatcheev, have shown that electromagnetic fields with a right-handed spiral twist do not interfere with normal vital functions, while those rotated in the opposite direction, i.e., to the left, produce negative effects capable of interfering with the normal functioning of cells.

Pulse emissions from Wi-Fi and DECT devices such as cordless phones and VoIP generate left-handed spiral fields, thus classifying them as harmful. Low-frequency electric fields cause biological tissues to heat up, interfering with cellular processes and altering them at the molecular level.

Over the years, Shungite has been subjected to several bioenergetic tests that have yielded very encouraging results, demonstrating that it is suitable for combating the harmful effects of electromagnetic waves generated by electronic devices.

This stone acts as a shield and a true transformer against electromagnetic radiation. One of the simplest and most affordable solutions, Shungite does not interrupt or stop electromagnetic waves but acts by transforming the direction of the spiral twist from left to right. This property most likely derives from the action of fullerenes, the famous molecules we discussed earlier. It is they that neutralize harmful effects, correct the direction of the twist, and restore energy and vitality to the body, rebalancing vital centers.

Copper Nugget - raw

Copper stimulates initiative, optimism, diplomacy, and independence.

It promotes a harmonious connection between the spiritual and astral bodies.

It is said to be a “bringer of good” because it brings benefits and good luck to its owner. An excellent conductor, it promotes the transfer of healing energy.

Dimensions: variable

Known since ancient times, copper was most likely the first metal used by humans.

Archaeological finds dating back as far as 10,000 years show how important its use was both in the construction of all types of equipment and in the manufacture of ornamental objects, and how important its use later became in the field of healing.

The Egyptians used copper in every field. They forged finely crafted bracelets that were certainly used for therapeutic purposes, and when ground into powder and mixed with other substances, they used it to prepare numerous medicines. In the Near East, it was used in the same way by the Assyrians, Medes, Sumerians, Hittites, and Phoenicians, the latter of whom exported it throughout the Mediterranean. Used by the Greeks and later by the Romans to prepare anti-inflammatory remedies, it was used on a large scale in the preparation of medicines, so much so that Pliny said, “Copper minerals provide for medicine in many ways, for in them is found the quickest cure for every type of ulcer.”

Today, numerous researchers and scientists are studying the possible applications of copper in the therapeutic field; modern science is now able to explain the mysterious influences that this metal has on our bodies.

Because copper is an excellent electrical and thermal conductor, it can be used in the manufacture of bracelets, which can act as receivers and capacitors because, composed of a single coil whose two ends (positive and negative poles) do not touch each other, they create an oscillating circuit that can detect harmful electrostatic charges in our bodies and discharge them. (The electrostatic charges that our bodies constantly absorb are harmful because they alter the electromagnetic and thermal balance of the cells, leading to degenerative conditions and biochemical imbalances in the body). Copper is important at every stage of development, from the fetal stage to old age, and a deficiency of this metal can be one of the contributing factors to many diseases. When wearing a copper bracelet, a dark mark may appear on the wrist, a clear sign that the copper is being absorbed through the pores of the skin, as perspiration dissolves infinitesimal percentages of the metal, allowing it to be absorbed by the body and, upon entering it, act as a trace element.

Copper is an extremely important trace element, so much so that there are excellent reasons to believe that this mineral trace can be valuable for maintaining balance in our bodies.

First of all, copper is necessary for fixing metals and minerals in our bodies; it is essential in the formation of blood because it binds iron to red blood cells, and it influences the pituitary gland, adrenal glands, and reproductive system. Furthermore, it binds calcium, catalyzes vitamin C, fights infections, and acts as a general tonic because it compensates for liver deficiencies.

A deficiency of this metal causes deterioration in various organic processes, leading to conditions such as anemia, insomnia, low blood pressure, osteoporosis, and irritability.

The presence of copper, on the other hand, prevents cellular oxidation and reduces liver damage and cirrhosis caused by the assimilation of carcinogenic substances.

Stone of Protection and Healing

It is also a wonderful stone of protection from physical and emotional harm, as it creates a shield against negativity by transforming and purifying negative vibrations within the environments in which we live. We can truly consider it as a “detergent” of negative energies, as it contributes to removing, as we said, not only negativity in the environment, but also that linked to one's own emotions, such as anger, jealousy, greed, resentment, envy, etc., strengthening emotional stability. This results in the ability to keep one's emotions in balance, avoiding “wild” mood swings that destabilize ourselves and those around us. Carrying or wearing Obsidian helps us to disperse those unkind thoughts that arise from within and reverberate outward into the world and onto the people who surround us.

It is very useful in all healing processes, as it helps to clarify the cause of the illness or disorder. In this way, it promotes subsequent improvement and makes us more receptive to the healing energies needed to create the right positive attitude in this regard.

Snowflake Obsidian and Physical Disorders

On a physical level, the stone acts on the vascular system, improving blood flow and working very well on veins and capillaries. The improvement of blood circulation will help warm the hands and feet of those who have them chronically cold. It also works on the skeletal system, on the skin, making it smooth, and supports the healing of wounds.

Mind and Emotions

On a mental and emotional level, it drives away fears of any kind and helps to release emotional blocks and traumas. It refines the mind and drives away stress. Furthermore, it is an excellent means to materialize and make ideas and projects tangible.
