Collection: Stromatolite

The etymology of the name stromatolite (or stromatolite) comes from the Greek “stroma” meaning carpet and “lithos” meaning stone (stromatolite is both a masculine and feminine name). Stromatolites are in fact geological structures caused by the biological activity of microorganisms.

Stromatolites are not the subject of any legend or associated myths. Indeed, we do not find any ancient writing describing them, however, they have a fascinating geological history. Archaeologists have managed to identify traces of this stone dating back 3.42 billion years across the world.

At that time, due to the moon (closer to the earth than today) and the rotation of the earth (a day lasted 28 hours), stromatolites could extend over larger areas. Additionally, the tides were higher.

Stromatolites result from the presence of unicellular microorganisms, called cyanobacteria. They are not algae (although they are called blue-green algae or green algae), they are unicellular or colonial bacteria. Cyanobacteria are probably the most successful living entities on the planet. It should be noted that they have survived the Earth's five mass extinctions. Cyanobacteria have largely been studied due to their presence in stromatolites through the fossilization process.

Stromatolites (or stromatolites or thrombolites) are laminar structures made of limestone, which are found in shallow aquatic environments, in seas, oceans and fresh waters. These are therefore limestone rocks with thin superimposed layers oscillating between organic and mineral. Stromatolites are of both biogenic origin (due to the presence of cyanobacteria) and sedimentary origin (due to this carbonate structure in the form of stacked sheets).

From the beginning of life on earth, cyanobacteria, a type of filament, extract carbon dioxide from water using the sun. Thus, these organisms have largely contributed to the creation of our atmosphere and the development of life by trapping calcium and carbon. Then the transformation into limestone occurs. Thus, this “algae” and sediments such as sand or mud calcify, forming sheets of limestone.

Underwater, stromatolites are alive. As soon as the water evaporates, the cyanobacteria die, the structure hardens and becomes a sedimentary rock including microscopic fossils of cyanobacteria.

In summary, stromatolite is a limestone fossil stone that develops in an aquatic environment. It has a hardness of 6.5 on the Mohs scale. The stone can have several colors, such as black, gray, yellow, brown. It is called laminated because it has the appearance of superimposed layers with alternating organic layers and clay-limestone layers.

The main deposits are in Brazil, etc.

In Lithotherapy, stromatolite is an anchoring stone and opens its wearer to wisdom. It facilitates personal development and the ability to adapt. It causes the person to open up to others, develops their compassion and empathy.

This stone offers a particular vision of the world, more focused on the community and the power of the collective. It allows us to act together in various fields, sporting or professional.

On a personal level, stromatolite helps to understand and accept the past in order to move forward in life. During therapy, it facilitates the understanding of blockages often linked to childhood. It is a stone of resilience.

Stromatolite strengthens self-esteem, confidence and self-assurance. It gives you the desire to undertake and have new goals, whether in terms of work or romantic relationships. It strengthens intuition and instinct.

This stone is a stone of protection against harmful energies, grudges and resentment. It dissipates negative emotions and replaces them with positive emotions. Thus, it raises the vibration rate which surrounds the wearer.

It is also very useful for children or adolescents in times of doubt, who do not find their place in their family (recomposed family, arrival of a little one or a little sister, etc.) or in society (at school, college) with the constant fear of being rejected.
