Physical properties
Hardness: 7 on Mohs scale; Color: Clear to milky white with black/brown branching inclusions; Luster: Vitreous; Crystal Structure: Trigonal; Specific Gravity: 2.65
Formation & geological history
Formed when mineral-rich water (carrying manganese or iron) flows through fractures in quartz, crystallizing into branching patterns called dendrites. Found globally in hydrothermal veins.
Uses & applications
Primarily used in jewelry (cabochons), as collector specimens, and in metaphysical practices.
Geological facts
The term 'dendrite' comes from the Greek word 'dendron' meaning tree, due to the plant-like appearance of the inclusions. Many people mistakenly think these are fossilized moss or plants.
Field identification & locations
Identify by looking for 'fern-like' or 'branching' patterns inside clear or translucent stone. Common in Brazil, India, and Madagascar. High-quality patterns are more prized.
