This necklace combines polished fossil coral, angelite, and unakite, set with sterling silver components. Each stone showcases unique geological features: fossil coral preserves ancient coral structures, angelite is a calcium sulfate mineral with a soft blue hue, and unakite is a metamorphic rock composed of pink feldspar, green epidote, and quartz.

Details:

• Material: Fossil coral, angelite, unakite, and sterling silver

• Appearance: Textured fossil coral with soft blue angelite and mottled green-and-pink unakite

• Formation: Fossil coral forms as silica replaces coral skeletons; angelite forms from the alteration of anhydrite in sedimentary deposits; unakite forms from metamorphosed feldspar-rich rocks

• Physical Properties: Fossil coral ~6.5–7, angelite ~3.5, unakite ~6–7 on the Mohs scale

• Educational Value: Demonstrates fossilization, mineral alteration, and metamorphic rock formation

This sterling silver fossil coral, angelite, and unakite necklace is a wearable collection of geological processes, blending natural history and mineral science in a visually striking piece.
