This piece is a polished labradorite specimen, showcasing the mineral’s signature labradorescence—flashes of iridescent color that appear as light interacts with layers within the stone. Labradorite is a feldspar mineral formed in igneous rocks and is valued for its striking optical effects.
Details:
- Mineral: Labradorite (NaAlSi₃O₈ – CaAl₂Si₂O₈)
- Size: Approximately 3 inches tall
- Appearance: Polished surface with gray to dark base color, displaying iridescent flashes of blue, green, gold, or orange when viewed from different angles
- Formation: Forms in slow-cooling igneous rocks, particularly gabbro, anorthosite, and basalt, where twinning and layering create labradorescence
- Physical Properties: Mohs hardness 6–6.5; vitreous to pearly luster; exhibits iridescent optical effect called labradorescence
- Educational Value: Demonstrates feldspar crystal structures, twinning, and optical phenomena caused by light interference in mineral layers
This polished labradorite piece highlights both the natural geological formation of feldspar and its unique visual effects, making it a striking display and educational specimen.
