Snowflake Obsidian Obelisk Point Natural Volcanic Glass Crystal Tower 75-100mm Polished Mineral Display Stone with Certificate

Description

Snowflake Obsidian Obelisk Point – Natural Volcanic Glass Mineral Tower

This listing features a genuine Snowflake Obsidian Obelisk Point, carved and polished from natural volcanic glass. The tower shape highlights the striking contrast between the deep black obsidian base and the distinctive pale grey mineral inclusions often described as snowflake patterns. These natural mineral formations create a unique appearance across the polished surfaces of the stone.

Each obelisk has been carefully selected for its natural pattern and mineral quality. The photographs included in the listing show an example of the actual specimen you will receive, with each piece displaying natural variation in the snowflake-like inclusions. The tower height ranges approximately 75–100mm, and full sizing details can be seen in the listing photographs.

This crystal includes a Certificate of Authenticity lifetime guarantee generic card, confirming the specimen is a genuine natural mineral.

Geological Classification and Composition

Snowflake Obsidian is a naturally occurring volcanic glass, formed from rapidly cooled silica-rich lava. Unlike crystalline minerals, obsidian lacks an ordered crystal structure and is classified as an amorphous igneous rock.

The distinctive pale patterns seen in Snowflake Obsidian are caused by crystallised inclusions of the mineral cristobalite, a polymorph of silica that forms during the cooling process within the volcanic glass.

Key geological characteristics include:

• Rock type: Volcanic glass

• Primary composition: Silicon dioxide (SiO₂)

• Structure: Amorphous (non-crystalline glass)

• Hardness: Approximately 5–5.5 on the Mohs scale

• Lustre: Vitreous or glass-like

• Fracture: Conchoidal fracture typical of volcanic glass

• Associated mineral inclusions: Cristobalite

The presence of cristobalite crystals produces the distinctive snowflake-like patterns embedded within the obsidian matrix.

Formation Through Volcanic Processes

Snowflake Obsidian forms when silica-rich lava cools extremely quickly during volcanic eruptions, preventing the development of a typical crystalline mineral structure. As the molten material solidifies, the glassy obsidian forms first.

During the cooling process, small areas within the obsidian may begin to crystallise, producing clusters of cristobalite crystals. These mineral clusters grow in radial patterns, forming the pale rounded inclusions that resemble snowflakes.

The geological sequence typically involves:

1. Rapid cooling of silica-rich lava forming obsidian glass

2. Gradual development of cristobalite crystals within the glass

3. Formation of radial mineral inclusions

4. Preservation of these patterns within the volcanic glass

These processes create the distinctive contrast between the black obsidian matrix and the pale snowflake formations.

Colour Characteristics and Natural Patterning

Snowflake Obsidian is known for its dramatic black and grey contrast, created by the interaction of volcanic glass and cristobalite mineral inclusions.

Typical visual features include:

• Deep black glassy volcanic base

• Pale grey or white cristobalite inclusions

• Rounded or radial snowflake patterns

• Smooth reflective surfaces when polished

The distribution of these snowflake inclusions varies naturally, ensuring that each specimen displays a unique pattern.

Obelisk Tower Shape and Lapidary Craftsmanship

The stone has been shaped into a polished obelisk point, a geometric form often used in lapidary work to showcase the natural textures and patterns of minerals and stones. Skilled cutting and polishing techniques reveal the snowflake patterns while maintaining the glass-like surface of the obsidian.

The obelisk tower typically features:

• Multiple polished faces

• A pointed apex

• Smooth reflective surfaces

• A stable flat base suitable for display

The polished surfaces allow light to interact with the volcanic glass, enhancing the contrast between the dark obsidian and lighter mineral inclusions.

Geological Occurrence

Snowflake Obsidian is commonly found in regions with historical rhyolitic volcanic activity, where silica-rich lava flows have cooled rapidly. These geological environments often occur in volcanic fields where lava domes and volcanic flows produced extensive obsidian deposits.

Such deposits form within volcanic terrains that include:

• Rhyolitic lava flows

• Volcanic domes

• Silica-rich magma systems

• Ancient volcanic ash layers

These conditions provide the ideal environment for obsidian formation and the development of cristobalite inclusions.

Collecting and Display Appeal

Snowflake Obsidian is valued among mineral collectors due to its distinctive volcanic origin and striking natural patterns. When carved into obelisk towers, the contrasting mineral inclusions become highly visible across the polished faces.

Collectors often appreciate Snowflake Obsidian for:

• Its volcanic glass composition

• Unique cristobalite snowflake patterns

• Natural contrast between dark and light minerals

• Distinctive geological formation

The obelisk form makes this specimen well suited for display in mineral collections, decorative interiors, or geological study displays.

Cultural and Traditional Context

In some crystal collecting traditions, Snowflake Obsidian is traditionally associated with balance and reflection, and may appear in symbolic or decorative displays. These interpretations reflect cultural traditions rather than scientifically established geological properties.
