This necklace features a fossilized ammonite paired with polished aventurine. The ammonite is a spiral-shaped marine fossil, while aventurine is a variety of quartz (SiO₂) containing mineral inclusions, often giving it a shimmering, green appearance.
Details:
-
Material: Fossilized ammonite and natural aventurine pendant
-
Appearance: Spiral ammonite fossil paired with green, slightly glittering aventurine
-
Formation: Ammonites formed in marine environments during the Mesozoic era; aventurine forms in quartz-rich rocks with mineral inclusions like mica or hematite creating its shimmer
-
Physical Properties: Aventurine hardness ~6.5–7; ammonite fossil varies depending on mineralization
-
Educational Value: Demonstrates fossilization, quartz formation, and the effect of mineral inclusions on color and optical properties
This ammonite and aventurine necklace combines ancient marine history with mineral science, creating a striking and educational piece.
