Raw Obsidian Glass Chunk

This item is a large, raw specimen of volcanic obsidian glass, characterized by its deep black color and brilliant vitreous luster. The object measures approximately 4 to 6 inches in height and exhibits prominent conchoidal fracturing across its surfaces, creating the sharp, curved ridges and wave-like patterns typical of rapid cooling volcanic material. The exterior shows a play between highly reflective, glossy facets and duller, matte areas where the surface is less newly exposed. Physically, it is an amorphous solid with an irregular, vertical silhouette. There are no visible maker's marks, as this is a natural geological specimen. The condition appears stable, though the edges are inherently sharp and prone to micro-chipping if handled roughly. The material shows a slight transparency along the very thinnest edges when back-lit, suggesting it may be a smoky or sheen variant. Its craftsmanship is defined by nature, evidencing the raw energy of its formation. It is a classic decorative mineral specimen that serves as a high-quality example of natural igneous glass.
