This necklace features polished fossil coral, agate, and jasper, set with sterling silver components. Each stone highlights distinct geological processes: fossil coral preserves ancient coral structures, agate is a banded microcrystalline quartz, and jasper is an opaque, patterned variety of chalcedony.

Details:

• Material: Fossil coral, natural agate, jasper, and sterling silver

• Appearance: Textured fossil coral paired with banded agate and earthy-toned jasper

• Formation: Fossil coral forms as silica replaces coral skeletons; agate forms from silica-rich fluids depositing in cavities; jasper forms as microcrystalline quartz with mineral impurities creating patterns

• Physical Properties: Agate and jasper hardness ~6.5–7; fossil coral ~6.5–7

• Educational Value: Demonstrates fossilization, quartz deposition, and how mineral impurities create patterns in rocks

This sterling silver fossil coral, agate, and jasper necklace combines natural history with mineral science, creating a wearable piece that is both educational and visually striking.
