Snowflake Obsidian is a type of volcanic glass that is primarily composed of silicon dioxide, with distinctive white or grayish “snowflake” patterns dispersed throughout its black or dark brown background. This unique appearance is caused by the presence of internal crystallites or phenocrysts, typically made of the mineral cristobalite. These white snowflake-like inclusions create a striking contrast against the dark base color of the obsidian, giving the stone its name.
Obsidian itself is formed when lava cools quickly and solidifies without crystallizing. The addition of these snowflake-like patterns distinguishes Snowflake Obsidian from other types of obsidian. The name “obsidian” is derived from the ancient Roman explorer Obsius, who is said to have discovered a similar volcanic glass in Ethiopia.
Beyond its aesthetic appeal, Snowflake Obsidian has been used for various purposes throughout history. In the realm of metaphysics and spirituality, it is believed to have grounding and protective properties. Some people use it for meditation and spiritual work, associating it with balance and the integration of opposites.
It’s important to note that while Snowflake Obsidian has cultural and spiritual significance for some, its use in these contexts is not universally accepted, and individual experiences with the stone can vary. As with any gemstone or crystal, beliefs and practices associated with Snowflake Obsidian can be subjective and depend on personal perspectives.

Geological Formation of Snowflake Obsidian
Snowflake Obsidian, like other types of obsidian, is formed through volcanic processes. Here’s a brief overview of the geological formation of Snowflake Obsidian:
- Volcanic Activity:
- Snowflake Obsidian is primarily created through the rapid cooling of lava. Volcanic activity results in the expulsion of molten rock, or lava, from the Earth’s mantle onto the surface.
- Composition:
- Rapid Cooling:
- Unlike many other rocks and minerals that form through slow cooling and crystallization, obsidian forms when lava cools rapidly. The quick cooling inhibits the crystalline structure from developing, resulting in an amorphous (non-crystalline) structure.
- Glassy Texture:
- The rapid cooling process prevents the formation of large crystals, giving obsidian its glassy texture. The lack of a crystalline structure is a distinguishing feature of obsidian.
- Inclusions:
- In the case of Snowflake Obsidian, the distinctive white or grayish “snowflake” patterns are caused by the presence of internal crystallites, often composed of the mineral cristobalite. These inclusions form as the lava cools and solidifies.
- Phenocrysts:
- The snowflake-like patterns are essentially phenocrysts within the obsidian. Phenocrysts are larger crystals that are embedded in a finer-grained matrix.
- Formation of Cristobalite:
- Cristobalite is a high-temperature polymorph of quartz, and its presence in the obsidian results from specific conditions during the cooling process.
- Erosion and Exposure:
- Over time, geological processes such as erosion and weathering expose the obsidian to the surface. This allows for the collection and extraction of Snowflake Obsidian by humans.
The unique combination of volcanic activity, rapid cooling, and the presence of specific minerals like cristobalite contributes to the formation of Snowflake Obsidian with its characteristic appearance. The intricate patterns within the black or dark brown matrix make it a popular and visually striking variety of obsidian used in various applications, including jewelry and spiritual practices.
Physical Properties of Snowflake Obsidian
The physical properties of Snowflake Obsidian are characteristic of volcanic glass and share similarities with other types of obsidian. Here are some key physical properties:
- Color:
- Snowflake Obsidian has a predominantly black or dark brown color, and its distinctive feature is the presence of white to grayish “snowflake” patterns created by inclusions of cristobalite.
- Luster:
- The luster of Snowflake Obsidian is typically shiny and glassy due to its amorphous, non-crystalline structure.
- Transparency:
- Snowflake Obsidian is generally opaque, meaning that light does not pass through it.
- Hardness:
- It has a hardness of approximately 5 to 5.5 on the Mohs scale. This means it is moderately hard and can be scratched by harder minerals but can scratch softer ones.
- Density:
- The density of Snowflake Obsidian varies but is generally around 2.35 to 2.40 grams per cubic centimeter.
- Cleavage and Fracture:
- Obsidian does not exhibit cleavage because it lacks a crystalline structure. Instead, it typically shows conchoidal fracture, characterized by smooth, curved, shell-like surfaces when broken. This fracture pattern is a result of the way the volcanic glass breaks along curved surfaces.
- Specific Gravity:
- The specific gravity of Snowflake Obsidian ranges from approximately 2.35 to 2.40, which is slightly higher than the average for most minerals.
- Toughness:
- Obsidian is known for its toughness. Despite its glassy appearance, it is less brittle than true glass. This toughness is due to its lack of cleavage and its ability to absorb stress before breaking.
- Tenacity:
- Snowflake Obsidian has a tenacious character, meaning it is resistant to breaking or shattering.
- Inclusions:
- The distinctive white or grayish “snowflake” patterns in Snowflake Obsidian are caused by inclusions of cristobalite, which is a polymorph of quartz.
These physical properties contribute to the unique appearance and durability of Snowflake Obsidian, making it a popular material for jewelry, carvings, and other ornamental uses. Additionally, its metaphysical properties and symbolism often enhance its desirability in the spiritual and healing communities.
