What is Malachite?

Malachite, an unmistakable green-coloured mineral, is the oldest ore of copper. It occurs close to the surface, and its presence often indicates deeper deposits of native copper are nearby.

An ore is a rock that contains a significant amount of a natural mineral with valuable elements that can be extracted. The extraction process from malachite involves heating the stone in conjunction with carbon. This is done at a relatively low temperature over a short period of time. 

Malachite often occurs alongside or in conjunction with azurite. The chemical formula for both minerals is almost identical. They're produced through the weathering of copper ore deposits.

When both minerals combine, the material is known as azurite-malachite.

The reason malachite is green and azurite is blue is because the copper in malachite is more highly oxidized than in azurite. Over time and under the right conditions, azurite can turn into malachite. This transformation is known as pseudomorphism, which literally means 'false form'.

In geology, pseudomorphs are minerals that have undergone a transformation whereby one changes into the other while retaining the external crystal shape of the original mineral. Azurite can alter to malachite through a chemical reaction that involves the addition of water and oxygen and the release of carbon dioxide. 

The process of pseudomorphism can vary greatly. One example is petrified wood. In this material, the original organic structure is slowly replaced by silica.

The History of Malachite

Although the use of malachite can be traced back to 8000 BC, it didn't start being used as an ore until 5000 BC. Until then, copper, which was the only metal known to humans, would have come from deposits of native copper.

Malachite was used as an ore of copper throughout antiquity. The ancient Egyptians had mining operations in place in the Sinai Peninsula in 4000 BC. This area was Egypt's main source of copper for thousands of years.

Many ancient civilizations used malachite for decorative purposes. It's also believed to have been the first green pigment. This led to it being used as a colouring agent in glazes, glass, and cosmetics.

In China, green pigment can be traced back to the Shāng people [c.1500 BC]. A tiger carved from malachite found in the tomb of a King's consort was dated to around the same period.

In western China, the colour green can be found in many paintings from the ninth and tenth centuries. It didn't become popular in Europe until around the 14th century. In ancient Egyptian tomb paintings, the colour green first appeared around 2613 BC.

Malachite beads found on the Euphrates River date back to 7000 BC.

When used as a pigment, malachite must be coarsely ground. This is because the colour will be much paler if particles are too small. 

The Pharaoh Amenhotep III used over five hundred kilos of mafek for inlay work in the Temple of Karnak. Mafek was a collective name for various green stones, one of which is believed to have been malachite.

Sorting objects into groups is an instinctive human characteristic. For thousands of years, rocks and minerals were grouped according to colour and visible properties. Records from the earliest system show two groups: 'stones' and 'earths'. Rocks and minerals were put into one group or the other depending on how they reacted to fire and water.

In the writings of Theophrastus, the ancient Greek philosopher, all bright green-coloured copper minerals were labelled as chrysocolla.

Pliny, the Elder Roman author and naturalist, suggested the name chrysocolla was more likely to refer to malachite. If true, that means it may not have included the mineral known today as chrysocolla.

In his works Naturalis Historia, Pliny also refers to a group of green-coloured stones as being different varieties of smaragdus. Many had little in common.  Smaragdus is an ancient name for emerald.

The group to which he's referring is believed to have included malachite, types of sapphire, turquoise, jasper, and possibly even glass.

Pliny wrote, "Copper smaragdus from Cyprus is associated with the colour blue." This seems to be a reference to the mineral azurite.

In the early 1800s, two enormous deposits of malachite were discovered in Russia. There was enough to supply the entire country with copper for around 170 years.

Many large slabs were polished for ornamental purposes, and malachite quickly became the stone of choice for the rich and famous.

Today, several of Russia's most important buildings are adorned with malachite. One is The Malachite Room at the Winter Palace in St Petersburg which features over 200 tons.

Saint Isaac's Cathedral in St. Petersburg was built over forty years starting in 1818. It features marble, granite, lapis lazuli and eight massive green malachite pillars.

More About Malachite

On the Mohs scale of hardness, malachite grades 3.5 to 4. As well as being very soft, it's also porous, so must be protected from moisture. Sudden exposure to heat can affect its colour or cause cracks. Malachite should not be allowed to get wet.

Despite being soft and fragile, malachite has always been a popular carving material. When used as a gemstone, it's cut as a cabochon.

The dust from malachite is highly toxic, so protective breathing equipment must be worn while it's being cut and polished. It's good practice to wash your hands after touching a freshly cut or dusty piece. Younger collectors should be informed not to put stones in their mouths or to get malachite wet. 

Malachite Healing Properties

Malachite is a stone of transformation believed to be useful for releasing emotional trauma and past wounds. It can help break negative patterns of behaviour and bring positive change.

It's associated with emotional balance, inner peace, and self-expression.

Malachite has protective qualities so may be used for shielding purposes to protect against negative energy.

A stone of spiritual evolution, malachite enhances the connection to higher realms of consciousness. It's associated with the heart chakra so promotes love, compassion and empathy.

A source of positivity and optimism, malachite imparts joy and a zest for life, transforming challenges into opportunities for growth and success.

It provides the motivation to strive for excellence and reach one's full potential. It inspires resilience and the ability to deal with obstacles effectively.

When used for manifestation, malachite can help bring desires and dreams into reality. With physical contact it amplifies the manifestation process, helping you achieve goals with greater ease.

Meditating with malachite brings feelings of comfort and familiarity. When held, it creates an empathic link to the subconscious. It brings forward memories and emotions from the past that are associated with happy moments.

Malachite acts as a catalyst, amplifying positive emotions and bringing back details that have long been forgotten. Through imagery and thought processes it makes happy memories more vivid and accessible.

Malachite should never be used as an elixir. This is water that's been infused with natural minerals to extract their healing properties. The water is then consumed.
