Collection: Dendritic chalcedony

Dendritic chalcedony is a particular variety of chalcedony, a form of microcrystalline quartz. It is distinguished by the presence of dendrites , mineral inclusions that form patterns resembling ferns, trees, or branching veins.

🌿 General characteristics

• Composition : Silicon dioxide (SiO₂), like all chalcedonies.

• Hardness : 6.5 to 7 on the Mohs scale.

• Color : Usually white, grayish, pale blue, or translucent, with black or brown patterns formed by the dendrites.

• Transparency : Translucent to opaque.

• Structure : Microcrystalline (crystals are invisible to the naked eye).

• Dendrites : These are not fossils or plants, but deposits of oxidized manganese or iron that form in fractures of the stone at the time of its crystallization.

🔍 Training

Dendritic chalcedony typically forms in cracks or cavities in volcanic or sedimentary rocks, where dissolved silica slowly precipitates. Dendrites appear when metal oxides migrate through the forming silica, creating these characteristic tree-like patterns.

💎 Uses

• Jewelry : Highly prized for its natural beauty and unique designs. Used in cabochons, pendants, rings, etc.

• Mineralogical collections : Each piece being unique, it is sought after by collectors.

• Lithotherapy

  • It is said to promote inner peace and personal growth .

  • Associated with natural wisdom , it would be linked to anchoring and connection to the Earth.

🌍 Deposits

Dendritic chalcedony is found in several countries:

• India

• Türkiye

• Russia

• Brazil

• Madagascar

• United States (especially Montana)

⚠️ Not to be confused with:

• Dendritic agate : Very similar, but the agate has a more zoned (banded) structure.

• Dendritic opal : another variety with dendritic patterns but amorphous (non-crystalline) structure.
