Genuine Snowflake Obsidian Worry Stone – Natural Volcanic Glass Palm Stone
This Snowflake Obsidian Worry Stone, also known as a palm stone, is a genuine natural volcanic glass specimen carefully shaped and polished into a smooth, tactile form. The photograph provided shows the exact specimen you will receive. Please refer to the images for full sizing and scale details.
This crystal includes a Certificate of Authenticity lifetime guarantee generic card confirming its genuine geological origin.
With its striking black surface patterned by distinctive white “snowflake” inclusions, this polished palm stone is both visually dramatic and geologically fascinating.
Geological Classification & Composition
Rock Type: Obsidian (Volcanic Glass)
Composition: Primarily Silicon Dioxide (SiO₂)
Structure: Amorphous (Non-crystalline)
Hardness: Approximately 5–5.5 on the Mohs scale
Lustre: Vitreous (Glassy)
Transparency: Opaque
Obsidian forms when silica-rich lava cools extremely rapidly, preventing the formation of a crystalline mineral structure. The rapid quenching process results in natural volcanic glass rather than a crystalline rock.
Snowflake Obsidian is a distinctive variety containing white or grey spherulites composed primarily of the mineral cristobalite. These radial crystal clusters form within the cooling glass, creating the characteristic snowflake-like patterns against the black background.
Formation & Volcanic Origin
Obsidian is typically associated with rhyolitic lava flows in volcanic environments. When molten lava with high silica content erupts and cools quickly upon contact with air or water, crystallisation is inhibited. This rapid cooling preserves the molten material in a glassy state.
In Snowflake Obsidian, the black volcanic glass later undergoes partial devitrification. During this process, microscopic crystalline growth occurs within the glass, forming spherical aggregates of cristobalite. These aggregates create the soft grey-white snowflake patterns that make this variety easily recognisable.
The contrast between the glossy black matrix and pale inclusions highlights its volcanic origin and natural formation process.
Worry Stone / Palm Stone Shape & Finish
This specimen has been polished into a classic worry stone or palm stone shape, designed for comfortable handling.
Notable features include:
-
Deep black glassy surface
-
Distinct white snowflake cristobalite inclusions
-
Smooth, polished finish
-
Rounded edges for comfortable grip
-
Flattened oval form suitable for palm use
Each piece is unique due to natural variation in spherulite size, placement and pattern density. The polished finish enhances the glassy lustre while clearly displaying the internal crystalline formations.
No artificial colouring or enhancement is implied; the patterns are entirely natural.
Collectibility, Display & Traditional Associations
Snowflake Obsidian is popular among mineral collectors for its striking contrast and volcanic origin. This palm stone format makes it suitable for:
-
Mineral and rock collections
-
Decorative display pieces
-
Educational geological study
-
Symbolic or spiritual practices
In various traditions, obsidian has been traditionally associated with grounding and protection in a spiritual sense. This listing focuses on mineralogical and geological characteristics only.
The smooth palm-sized shape also makes it an appealing gift for collectors and enthusiasts of natural volcanic materials.
Authenticity & Presentation
This Snowflake Obsidian Worry Stone has been carefully selected for clear pattern definition, strong colour contrast and overall polish quality. The image shown is of the exact specimen you will receive.
Included with your purchase is a Certificate of Authenticity lifetime guarantee generic card confirming this is a genuine Snowflake Obsidian specimen.
A striking example of natural volcanic glass with cristobalite inclusions, this authentic Snowflake Obsidian palm stone combines geological intrigue, bold natural patterning and refined craftsmanship in one distinctive collector’s piece.
