Black Obsidian Platonic Solids Set – 5 Pieces

Product Description

This five-piece Black Obsidian Platonic Solids Set combines deep black volcanic glass with five classic geometric forms. Smooth, polished faces reflect the light, bringing definition to each shape’s edges and angles.

The set includes a tetrahedron, cube, octahedron, dodecahedron and icosahedron. Display the forms together, explore their geometry or incorporate them into meditation and crystal grids.

Composition & Formation

Obsidian is a naturally occurring volcanic glass formed when lava cools rapidly, preventing substantial crystal growth. Unlike crystalline minerals such as quartz, it has an amorphous structure.

The geometric shapes in this set are carved and polished rather than naturally formed crystals.

Metaphysical Properties — Traditional Associations

In crystal traditions, Black Obsidian is associated with grounding, protection and self-reflection. Some people use it during meditation as a symbolic focus for exploring personal boundaries and setting intentions.

The Platonic solids are used in sacred geometry practices to represent the elements. These meanings are spiritual interpretations rather than scientifically established effects.

Chakra Association

• Root chakra — traditionally associated with grounding and stability.

Zodiac Connection

• Scorpio

• Sagittarius

Zodiac associations vary between crystal traditions.

Element

• Black Obsidian: traditionally associated with Earth and Fire.

• Platonic solids: tetrahedron — Fire; cube — Earth; octahedron — Air; icosahedron — Water; dodecahedron — Ether or Spirit.

Crystal Pairing

Within crystal practice, pair with Hematite for a grounding theme or Rose Quartz for an intention centred on compassionate self-reflection.

What You Will Receive

One five-piece Black Obsidian set containing:

• One tetrahedron — four triangular faces.

• One cube — six square faces.

Obsidian is brittle and can produce sharp edges if chipped or broken. Store the pieces with soft padding to protect their polished surfaces.

Frequently Asked Questions

What is a Black Obsidian Platonic Solids Set?
It is a collection of the five classic Platonic solids carved from Black Obsidian volcanic glass.

Is Black Obsidian a crystal?
Scientifically, obsidian is volcanic glass with an amorphous structure. It is commonly grouped with crystals in retail and spiritual practice, but it is not a crystalline mineral.

What are Platonic solids?
They are the five regular convex polyhedra. Each form has identical regular polygon faces, with the same number of faces meeting at every vertex.

Are the geometric shapes naturally formed?
No. The five forms are carved and polished from obsidian.

What can I use this set for?
Use it for decorative display, exploring geometry, meditation or arranging crystal grids.
