Stone of the Month September 2021: Gabbro (Mystic Merlinite)

English Version here

Now is the time of harvest - both the grain in the field and the fruits of our labor are being brought in. Slowly, but noticeably, the days are getting cooler and the nights longer. This time of transition is marked by the transformation of nature, which is now which is now preparing for darker times. We can take stock - what have we achieved, where is there still work to be done? The equinox balances the exuberance of summer with the barrenness of winter.

Gabbro accompanies us at this time to start with new things. Even if we have the feeling that everything runs in orderly courses, one or the other new project must be started. Let's listen to ourselves - what needs have been left unfulfilled have remained unfulfilled so far and what can we do to fulfill them? Now is the time for careful planning, because there is not so much time left until the end of the year.

Name and varieties

Gabbro was named by the German geologist Christian Leopold von Buch (1774 - 1853) after the locality of Gabbro near Florence. Gabbro is also sold in retail as well as wholesale under the name Mystic Merlinite.

The variety "Black Galaxy" (Bronzite Gabbro) is a dark, almost black rock and is mined since 1988 in Andhra Pradesh in India. In the trade it comes under the name "Black Galaxy", "Star Galaxy" and "Gold Galaxy". Under these names it is known among stonemasons as a decorative stone, which is good for making kitchen tiles and countertops. Mineralogically, it is Gabbro.


Meaning and use of Gabbro

Gabbro shows good stability against weathering and is therefore popular for use as crushed stone and for cladding. However, gabbro also contains traces of Kcopper, platinum and silver, chromium, nickel and titanium and is a sought-after Raw material for the extraction of these metals.

It is only in the last few decades that Gabbro has been discovered as a gemstone by the stone healing community.

Association and Application

In stone healing, Gabbro stands for new beginnings. In times of tiring routine, the stone has a strengthening effect and encourages you to listen to yourself and perceive your own needs. It helps to carefully plan and prepare new things. With important changes, such as a move or a change of job, Gabbro provides the best possible support. The stone helps in situations where the change has already occurred due to external circumstances and one must now also mentally to the new circumstances. Gabbro promotes the necessary courage and optimism to be able to realize great plans.

The self-healing powers and the ability to regenerate are also supported by Gabbro; the stone gives a pleasant body feeling. Some users therefore put Gabbro in the sauna or in the bedroom. Like all stones of plutonic origin, Gabbro also strengthens the unity and firm connection of body and mind.

Gabbro and Basalt 

Gabbro is a coarse-grained igneous rock of plutonic origin, meaning it crystallizes from a magma deep in the earth's crust. When the magma escapes to the earth's surface during a volcanic eruption, basalt is formed instead of gabbro. Gabbro is thus the plutonic counterpart of basalt, its chemical composition is exactly the same as that of basalt, the only difference between the two being their formation.

Externally, however, basalt and gabbro are quite distinct.
Gabbro has a crystalline structure, recognizable by the color variations visible to the naked eye, while basalt has a more homogeneous appearance.
