A truly unique, conversation-starting piece made from genuine fossil walrus ivory, cut and polished into a natural cross-section and finished as a brooch. The organic, freeform shape highlights the distinct inner core (osteodentine)—that textured, crystalline-looking center—surrounded by smooth, creamy outer ivory. This isn’t just jewelry—it’s a slice of ancient history. * Carved from a walrus tusk that has been fossilized (naturally aged underground for hundreds to thousands of years) * The tusk was cross-cut, revealing the signature two-layer structure: * Outer smooth ivory (primary dentine) * Inner granular core (unique to walrus ivory) * Then hand-shaped, sanded, and polished, preserving its natural form rather than overworking it * Fitted with a pin back to create a wearable art piece * Fossil walrus ivory is typically recovered from Arctic regions (Alaska/Siberia) * These tusks are not modern—they are generally 300 to several thousand years old * Naturally mineralized over time, which gives the warm tone and subtle variations you see * Material: Genuine fossil walrus ivory * Color: Creamy ivory with natural tan undertones * Features: Visible inner core / organic patterning * Style: Organic, artisan, natural specimen jewelry * Closure: Pin back (brooch) * Condition: Excellent vintage condition; natural inclusions consistent with fossil material
