Collection: Obsidian

Obsidian is a fascinating volcanic rock, both mysterious and aesthetically striking. Here's a look at its main characteristics and what makes it so special.

🌋 Geological origin

• Formation: Obsidian forms during the rapid cooling of silica-rich lava (often of rhyolitic origin), which prevents crystallization. The result is a natural volcanic glass .

• Appearance: It is generally black, but can have various shades depending on the inclusions: dark green, brown, red, gold or even iridescent (rainbow).

• Structure: Amorphous (without crystals), conchoidal fracture (like glass), very sharp.

🛠️ Use in the story

• Prehistory: Used to make tools and weapons (arrowheads, knives) because of its exceptional sharpness.

• Mesoamerica: Civilizations like the Aztecs and Mayans used it for ritual instruments and mirrors.

• Modern surgery: Obsidian scalpels are still used in some settings because their edge is finer than that of steel.

💎 Spiritual and symbolic properties (lithotherapy)

• Protection: Black obsidian is said to repel negative energies and act as a “shield.”

• Revelation: It would help to reveal the truth, to bring up hidden traumas to better heal them.

• Grounding: Strengthens the connection to the Earth and helps you stay centered.

🧪 Technical characteristics

• Composition: Mainly silica (about 70–75%).

• Hardness: About 5–5.5 on the Mohs scale.

• Density: 2.3 to 2.6 g/cm³.

🧭 Varieties of Obsidian

• Black Obsidian : The most common.

• Snowflake Obsidian : With white inclusions of cristobalite.

• Golden or silver obsidian : Shimmering effects due to tiny gas bubbles.

• Rainbow Obsidian : Multicolored reflections, highly prized in jewelry.
