This remarkable cassiterite is a single crystal with an intense black color reminiscent of India ink. It is beautifully formed with sharp terminations that are highlighted by a gleaming luster. Sleek and dark, it is contrasted by its matrix of silvery muscovite. Its mirror-like faces catch the light beautifully, revealing the elegant symmetry for which this species is prized.
On closer inspection, you can spot tiny stepped facets known as vicinal faces. These minute, shallow planes form as microscopic growth steps advance across the crystal during its formation, capturing subtle changes in its geologic environment.
The result is a petite specimen that is both commanding in presence and fascinating in detail. With its lustrous form, distinctive growth textures, and superb size, this specimen is a standout example of its kind.
