Introduction to the Meaning and Uses of Malachite

Malachite, with its beautiful, rich green color, leaves no doubt of its importance as a jewel. Its opaque strength and power demands respect, mesmerizing the viewer. Yet the movement, flow and energy in its lines, circles and designs soothe and welcome. It is spiritually inviting.

Malachite personifies the deep healing green of nature and represents the innate beauty of flowers, trees, roots and plants. It manifests a deep Devic green which rules the material plane. [Raphaell, 144] It is a Stone of Transformation, assisting one in changing situations and providing for spiritual growth. [Melody, 395] It heals on physical and emotional levels, drawing out impurities and stimulating the Life Force throughout the aura and body. [Ahsian, 248]

The name Malachite may come from the Greek word malakee, or malache, signifying the resemblance of Mallow leaves, or from the Greek word malakos, meaning soft. [Fernie, 167][Simmons, 247] Being a carbonate of copper, Malachite is sometimes intergrown with Azurite, forming Malachite-Azurite, or with Chrysocolla, forming Malachite-Chrysocolla. [Simmons, 247]

Well known to ancient Egyptians, Malachite mines were in use between the Suez and Sinai as early as 4000 B.C. [Kunz, 97] It was also popular with the ancient Greeks and Romans, for jewelry, ornaments, and in powdered form, for eye shadow. In the Middle Ages, Malachite was believed to protect against the "Evil Eye" and to cure various stomach ailments. Russian czars used Malachite for ornaments and paneling for their castles, and intricate inlay work. [Simmons, 247]

Inherent in Malachite is lighter green eye-shaped forms or bands on its surface. These "eye stones," believed to enhance great visionary powers, were used to ward off negative happenings. They were stones of security and protection for children, and their most remarkable association today is the ability to warn of impending danger by breaking into pieces. [Mella, 90]

Malachite Healing Therapies - Overview

Malachite must be handled with caution!

Malachite is toxic and should be used only in its polished form. Avoid breathing its dust. [Hall, 185]

Physical Healing Energy

Malachite is an effective remedy for female problems, especially regulating the menstrual cycle and cramps, and for easing labor. [Megemont, 119] It has been called the Midwife Stone. It resonates with the female sexual organs, and treats sexual dis-ease, especially when caused by traumatic past experiences. [Hall, 184]

It fights osteoarthritis, most notably in the spine, and strengthens memory, especially for those with short-term memory loss who forget the names of people right after hearing them. [Megemont, 119-120]

Known to lower blood pressure, Malachite also treats epilepsy, travel sickness and vertigo. It helps in the healing of fractures, swollen joints, growths, tumors, torn muscles and broken bones. It enhances the immune system and stimulates the liver to release toxins. [Hall, 184-185][Eason, 283]

We must again warn you: use only polished Malachite. Do not use any Malachite elixir. Do not place any malachite in your mouth. If you use this stone, use common sense. Place it on the body with a small cloth under it. It's healing powers will not be diminished.

Emotional Healing Energy

As a stone of transformation, Malachite encourages change and emotional risk-taking. It shows what is blocking your spiritual growth, draws out deep feelings and psychosomatic causes, then allows you to break unwanted ties and outworn patterns. It encourages the expression of feelings, alleviating shyness and teaching the responsibility for one's own thoughts and actions. It supports friendships and empathy for other people. [Hall, 183-4]

Malachite helps battle depression and anxiety, gives resistance to emotional blackmail and heals emotional abuse, especially when suffered in childhood. It also encourages healthy relationships based on love and not need. [Eason, 283] Malachite assists in overcoming fear of confrontation, or fear of being seen or noticed, and helps one find the strength within to assume their rightful place in the Universe. [Ahsian, 248]

Chakra Healing and Balancing Energy

With its pure energy rays of green, Malachite is dedicated to the Heart Chakra. Located near the center of the breastbone, it regulates our interaction with the external world and controls what we embrace and what we resist. It gives us the balancing ability to be ourselves within the environment. When the heart chakra is out of balance you may feel either controlling or controlled in a relationship, and become critical of the little foibles of others. You may well find yourself having inappropriately strong emotional responses to everyday external stimuli.

Green crystal energy is used to resolve blockages and to re-balance the heart chakra, helping us understand our own needs and emotions clearly. We can deal with the ebbs and flows of emotional relationships, understand their cyclic nature, and accept the changes.

Malachite is helpful to clear and activate other chakras. Placed on the Third Eye, it activates visualization and psychic vision. Placed on the solar plexus, it facilitates deep emotional healing, releasing negative experiences and old traumas. [Hall, 183]

Spiritual Energy

Malachite has the ability to serve different purposes for different people. For those highly evolved and dedicated to humanitarian purposes, it assists in grounding higher energies onto the planet for those purposes. For those in a purification process, Malachite acts as a purger and a mirror to the subconscious, reflecting into the conscious mind that which needs to be cleansed.

This stone is dense and nontransparent, absorbing energy instead of emitting it. Place Malachite stones over areas that are diseased or painful, to draw out the negative energy and surface the causes for it. Because of the absorbing properties, it is important to cleanse the stones after such use. [Raphaell, 144]

Malachite can be a powerful ally for those waiting for their reality to change. It reminds us we have come here to co-create with the Universe, and helps in identifying the steps necessary to bring dreams, visions and wishes into physical reality. [Ahsian, 248]

Malachite stimulates dreams and brings memories vividly to life. [Hall, 184] It is also an excellent stone for the re-birthing process, providing easy disposal of opposing encounters. [Melody, 395]

Color Energy

Malachite, with its pure Green Ray of Influence, is a "growth crystal" - a powerful conduit of the earth's Life Force of birth, development, and creation, and of the power of nature's constant renewal. It is a potent aid in nurturing, whether of fledgling family relationships or a new business venture.

Green talismans are perfect for keeping a venture on course, a project on schedule, and life on track. Lighter Malachite crystals promote spiritual growth and renewed commitment to a higher purpose. Those of a darker hue are talismans of physical growth and strength, and safety in travel.

Meditation with Malachite

Malachite reveals the truth about oneself and brings to the surface that which is unknown or unseen to the conscious mind. When used, worn or meditated upon, it will draw out and reflect whatever is impeding spiritual growth, and is best used in conjunction with meditation to help balance and release the debris that is revealed. [Raphaell, 145]

To break negative patterns of behavior, speak your fears and sorrows aloud daily as you hold the crystal, then, leave it in a sheltered place outdoors overnight to carry away the fears. [Eason, 283]

Some practitioners have used Malachite in meditations to get in touch with the Earth Mother. Holding one and sitting quietly on the ground for a few minutes helps many people to be more aware of the earth as a living organism upon whom we are totally dependent.

Divination

Malachite can be used for scrying. Journeying through its convoluted patterns releases the mind, assisting in receiving insights from the subconscious or messages from the future. [Hall, 183]

Malachite and the Angelic Realm

If your birthday falls in any of the following periods, a Malachite can be a valuable conduit to your Guardian Angel. The table also provides the name of the Guardian Angel of those born in the time period.

Malachite Amulets and Talismans

Malachite was considered to be a talisman for children. If a piece of the stone were attached to an infant's cradle, all evil spirits were held aloof and the child slept soundly and peacefully. In some parts of Germany, Malachite shared with Turquoise the repute of protecting the wearer from danger in falling, and also gave warning of approaching disaster by breaking into pieces. [Kunz, 97]

At one time, the appropriate design to be engraved upon a Malachite was the image of the sun. Such a gem would become a powerful talisman and protected the wearer from enchantments, evil spirits, and from the attacks of venomous creatures. [Kunz, 97] Because of Malachite's peculiar markings, some of which suggest the form of an eye, Malachite was worn in parts of Italy as an amulet to protect the wearer from the spell of the Evil Eye. Such stones were called "peacock-stones," from their resemblance in color and markings to the peacock's tail. The form of these Malachite amulets is usually triangular and mounted in silver. [Kunz, 137]

Malachite is a Guardian Builder Crystal. The Guardian talismans do not reveal their inner strength. These stones rarely, if ever, form transparent crystals. Rather, they hide their strength behind an opaque mask, obscuring the power they possess. In the physical world they are fantastic amulets for protecting your loved ones, your possessions, and your physical security.

Combined with the Earth Power of a Builder, these crystals are perfect aids in building up wealth, or improving our lot in life both materially and spiritually. They help in development efforts, in learning new skills and knowledge, and in building new relationships.

Feng Shui

Malachite utilizes Wood energy, the energy of growth, expansion, new beginnings, nourishment and health. It enhances vitality, brings abundance, and keeps us growing physically. Use green crystals to enhance any space used for eating, in the room of a small child, or in a place of your home where you are beginning a new project. Wood energy is traditionally associated with the East and Southeast areas of a home or room. It is associated with the Family and Health area, and the Prosperity and Abundance area.

Ancient Lore and Legend

Malachite is one of the oldest known stones, used for thousands of years for its healing and transforming properties. In ancient Egypt, Malachite was used by the upper classes as one of their main power stones, serving as a grounding force to help them channel higher energies onto the planet.

The pharaohs often lined the inside of their headdresses with Malachite, believing it helped them rule wisely. [Raphaell, 143] It was also pulverized into a fine powder and used as a brilliant eye shadow. This green adornment was not only cosmetic, it was reported to stimulate clear vision and insight. [Mella, 90]

In Switzerland and in several villages of Savoie in the French Alps, Malachite crosses are thought to bring good luck to pregnant women, and mothers of large families are proud to show their collections of Malachite crosses. Collectors have crosses that date back to the fifteenth century. [Megemont, 119] It was believed that a piece of the stone attached to an infant's cradle, would keep away all evil spirits and the child would sleep soundly and peacefully. [Kunz, 97] The gemstone was often worn by children as a talisman, protecting them from bad dreams while giving them a greater sense of emotional security. [Mella, 90]

Malachite is one the stones dedicated to Saint Francis of Assisi. The association is so great, that legend claims Malachite, held in the hand or worn as a jewel, will enable one to understand the language of the animals, and if one regularly drinks from a cup made of Malachite, it is possible to communicate with them. [Megemont, 119]
