Black Rock with White Veins - Natural Mineral Specimen for Collection or Display #167555 (License: Personal Use)

The specimen displays a rugged, asymmetrical form with a predominantly dark matrix intersected by fine, branching white fibers-likely quartz or calcite infill in a metamorphic or volcanic host rock. Its surface is uneven and tactile, suggesting minimal polishing to preserve natural texture and diagnostic features. The contrast between the deep gray-black base and luminous white filaments makes it an excellent teaching tool or display piece.
