This natural black tourmaline specimen displays dense clusters of sharply formed prismatic crystals with a deep black to charcoal grey colour and a subtle metallic sheen. The surface shows strong vertical striations typical of tourmaline, giving the piece a rugged and highly textured appearance.
 
Interlocking crystal formations create depth and complexity throughout the specimen, with broken crystal faces and layered growth clearly visible. Small areas of warm brown and orange mineral inclusions can be seen within the crevices, highlighting the natural environment in which the crystals formed.
 
Tourmaline is a complex boron silicate mineral, and black tourmaline, also known as schorl, is one of the most common and recognisable varieties. This specimen has been left completely natural, making it well suited for mineral collectors and those who appreciate raw crystalline structure.
