Mineral Type & Scientific Classification

Black Tourmaline is scientifically known as Schorl, a member of the tourmaline supergroup. It is a complex boron silicate mineral typically containing sodium, iron, aluminium, silicon, oxygen, and hydroxyl groups. Its general formula is:

NaFe₃Al₆(BO₃)₃Si₆O₁₈(OH)₄

Tourmaline crystallises in the trigonal crystal system and commonly forms elongated prismatic crystals with vertical striations along the length of the crystal. In tower form, the material has been cut and polished from natural rough while retaining the dense, opaque character of Schorl.

Black Tourmaline has a Mohs hardness of approximately 7–7.5, making it a durable mineral suitable for carving and long-term display.

Colour, Texture & Surface Features

This Black Tourmaline tower displays:

• Deep opaque black colouring
• Fine-grained to slightly fibrous internal structure
• Smooth polished faces
• Defined geometric point

In natural crystal form, Schorl often shows strong vertical striations. While these may not be fully visible in a polished tower, the internal structure contributes to its dense, solid appearance. The polished finish enhances its uniform dark tone and provides a refined surface suitable for display.

Geological Formation

Black Tourmaline forms primarily in pegmatitic and hydrothermal environments, where boron-rich fluids interact with cooling magma or surrounding rock. Pegmatites, known for producing large and well-developed mineral crystals, are a common source of tourmaline.

Schorl is frequently found associated with quartz, feldspar, mica, and other pegmatite minerals. Over geological timescales, crystallisation occurs as mineral-rich fluids cool and solidify, allowing tourmaline crystals to develop within fractures and cavities.

The material used for this tower has been cut from naturally formed Black Tourmaline rough.

Tower Form & Traditional Associations

The tower or point shape is a crafted geometric form designed with a flat base for upright stability and polished faces that converge toward a defined apex. This shape highlights the mineral’s natural colour and creates a strong, structured silhouette.

Black Tourmaline has been traditionally associated with protection and grounding in spiritual symbolism. These interpretations are cultural and symbolic rather than scientific.

This Black Tourmaline Tower is suitable for:

• Mineral and crystal collections
• Pegmatite mineral enthusiasts
• Decorative home or office display
• Meditation or spiritual spaces
• Unique natural gifts
