This necklace features polished fossil coral, quartz, and unakite, set with sterling silver components. Each stone illustrates a different aspect of geological formation: fossil coral preserves ancient marine life, quartz is a widely occurring crystalline mineral, and unakite is a metamorphic rock composed of green epidote, pink feldspar, and quartz.
Details:
-
Material: Fossil coral, natural quartz, unakite, and sterling silver
-
Appearance: Textured fossil coral paired with clear or lightly colored quartz and green-and-pink unakite
-
Formation: Fossil coral forms as silica replaces coral skeletons; quartz crystallizes from silica-rich fluids; unakite forms from metamorphism of feldspar-rich rocks with epidote
-
Physical Properties: Quartz and unakite hardness ~6.5–7; fossil coral ~6.5–7
-
Educational Value: Demonstrates fossilization, mineral crystallization, and metamorphic rock formation
This sterling silver fossil coral, quartz, and unakite necklace combines natural history and mineral science, creating a visually appealing and educational piece.
