Agate – Atlantis Institute Crystals Encyclopedia


Agate is a crystal of primary formation which means it was formed from molten magma. This usually happens in cavities in volcanoes where the combination of chemistry and structural arrangements of mineral deposits, atoms and substances pass from gas or liquid into a solid state or by means of going out of solution by precipitation or evaporation.

Agate is made up of silicon dioxide, a variety of Chalcedony, which is a part of the Quartz family. The intricate bands found in Agate crystals are said to result from saline water trapped in the gas. When it starts to cool, it begins to fight the iron in the lava by pushing off the walls of its cavities, creating a rippling effect and subsequent beauty in its formation.

Although Agate crystals are often found in volcanic rocks, they can also be found in many other rocks, including metamorphic rocks.

All crystals belong to a different group according to the basis of the relationships of their axes. There are seven systems and 32 classes of symmetry. Agate crystals belong to the Trigonal system.


Ancient myth tells the story of this interesting and unique crystal stone being found in the Achates river in Sicily, which was a Greek colony at the time.

The river is now known as the Drillo River, but the old Greek word ‘Agateec’, which means happy, was adopted as this beautiful crystals name. A greek philosopher named Theophrastus is said to have discovered the stone between the 4th and 3rd centuries BC.

Agate is said to have been widely used in ancient Egypt and became popular throughout the middle ages in Europe. It has grown in popularity over the years mainly due to its unique and interesting designs. Agate and its different variants are now widely sought throughout the world.

Medieval civilisations used agate to give protection from danger and bring victory and strength; it also was used to bring favour with the Gods.

Agate was also discovered amongst Neolithic artefacts. Agate has a lower intensity and vibration than most, yet is regarded as being grounded and stabilised.


In their raw form, they are rough and need to be polished down to reveal the stone's true form and unique style. They come in many different colours, and each one will be different in design. Many Agate crystals have a band-like design running through them, somewhat similar to the rings on an old tree.

A very strong stone and is specifically good at resisting acids. It is also widely used to create ornaments and jewellery. Comes in a variety of shapes, sizes and patterns and is known for its glass-like appearance when polished.

Esoteric Attributes

By their very nature, Crystals can receive and focus energy in different ways. Their molecular structure enables them to be used to amplify and convert energy. Hence, crystals have been used for centuries to aid healing and transmute energy both in the metaphysical and physical world.

Because each crystal family has different formational backgrounds, each also has different vibrational frequencies that can be harnessed and used for specific purposes. Each, therefore, has specific qualities that can be used to help a person heal on the many different levels of their being.
