Description
Black Obsidian Merkaba Star – Natural Volcanic Glass Crystal Carving
This Black Obsidian Merkaba Star is a genuine natural volcanic glass specimen carved into a geometric sacred geometry form. Measuring approximately 10–20mm, this compact piece highlights the deep black colour and smooth reflective surface characteristic of natural obsidian.
The Merkaba star design is created from two interlocking tetrahedrons forming a three-dimensional star. When carved from natural stone, the shape emphasises symmetry and geometric precision while showcasing the mineral’s natural colour and texture.
Each specimen is carefully selected to ensure consistent quality and appearance. The photographs in the listing show an example of the actual specimen you will receive, selected from the same group of natural obsidian pieces and within the stated size range.
This crystal includes a Certificate of Authenticity lifetime guarantee generic card, confirming that the specimen is a genuine natural mineral. For exact dimensions and proportions, please refer to the photographs included in the listing.
Mineral Type and Geological Classification
Obsidian is a naturally occurring volcanic glass formed from rapidly cooled silica-rich lava. Unlike most minerals, obsidian does not develop a crystalline structure because the lava cools too quickly for crystals to form.
Key geological characteristics include:
- Material Type: Natural volcanic glass
- Composition: Primarily silicon dioxide (SiO₂)
- Structure: Amorphous (non-crystalline)
- Mohs Hardness: Approximately 5–5.5
- Lustre: Vitreous (glass-like)
- Transparency: Usually opaque to slightly translucent on thin edges
Because it lacks a crystal lattice, obsidian fractures with a distinctive conchoidal fracture, producing smooth curved surfaces similar to broken glass.
Formation of Obsidian in Volcanic Environments
Obsidian forms when felsic lava rich in silica erupts and cools extremely rapidly. This rapid cooling prevents the atoms in the molten rock from organising into a crystalline mineral structure.
Instead, the molten material solidifies directly into volcanic glass. This process typically occurs in environments such as:
- Rhyolitic lava flows
- Volcanic domes
- Obsidian lava fields
- Volcanic glass deposits along lava margins
Because obsidian cools quickly at the Earth’s surface, it preserves a glass-like structure and smooth texture. Trace elements and tiny mineral inclusions can occasionally produce subtle variations in colour and pattern within the stone.
Black obsidian is the most common variety, formed from silica-rich magma with relatively low concentrations of additional mineral impurities.
Colour, Texture and Surface Characteristics
Black obsidian is recognised for its deep black colour and glassy reflective surface. When polished or carved, the stone develops a smooth finish that highlights its natural volcanic origin.
Typical features include:
- Rich black colouration
- Smooth polished surface
- Glass-like vitreous lustre
- Dense, uniform appearance
- Curved fracture patterns in raw material
Because obsidian forms naturally from volcanic processes, each specimen may display subtle internal variations that reflect the lava’s cooling history.
Merkaba Star Geometry and Crystal Carving
This specimen has been carved into a Merkaba star, a geometric form consisting of two interlocking tetrahedrons. The resulting structure creates a three-dimensional star shape with multiple triangular faces.
The Merkaba design is widely recognised within sacred geometry traditions and is appreciated for its symmetrical mathematical form.
Features of the carving include:
- Interlocking tetrahedral geometry
- Precisely carved triangular faces
- Balanced three-dimensional structure
- Compact collectible size suitable for display
Carving obsidian requires careful shaping and polishing to achieve the clean edges and smooth surfaces characteristic of this geometric design.
Authenticity and Specimen Details
This item is a genuine Black Obsidian volcanic glass specimen.
Included with the crystal:
- Natural Black Obsidian Merkaba star
- Approximate size 10–20mm
- Carefully selected volcanic glass specimen
- Certificate of Authenticity lifetime guarantee generic card
Natural variations in tone, minor inclusions, and subtle surface differences are normal characteristics of obsidian and reflect its volcanic origin.
The photographs in the listing show an example of the specimen you will receive, ensuring consistent size and quality.
Mineral Collecting and Decorative Display
Obsidian has been valued historically for its unique volcanic origin and striking glass-like appearance. Because of its ability to fracture into extremely sharp edges, obsidian was also widely used by ancient cultures to create cutting tools and ceremonial objects.
Today, polished obsidian carvings are popular in mineral collections and decorative displays due to their distinctive appearance and geological interest.
This Black Obsidian Merkaba Star is suitable for:
- Mineral and crystal collections
- Geological study displays
- Sacred geometry collections
- Decorative natural stone arrangements
- Unique gifts for mineral enthusiasts
In some traditions, Merkaba star shapes and obsidian stones are traditionally associated with symbolic or spiritual themes, and carved stones of this form are sometimes displayed for their geometric significance.
With its deep black colour and precise geometric carving, this Black Obsidian Merkaba Star provides a distinctive volcanic glass specimen and a visually striking addition to any mineral or crystal collection.
