This sphere is carved from malachite, a copper carbonate mineral recognized for its vivid green color and distinctive banded patterns. Malachite forms near copper deposits through the weathering and oxidation of copper ores, often creating striking concentric or swirling designs.
Details:
- Material: Malachite (Cu₂CO₃(OH)₂)
- Size: Approximately 1.5 inches in diameter
- Appearance: Polished sphere with rich green hues and banding that may appear as rings, swirls, or layers
- Formation: Develops in the oxidation zones of copper ore deposits, frequently alongside azurite, chrysocolla, and other secondary copper minerals
- Physical Properties: Mohs hardness 3.5–4; silky to vitreous luster; opaque with distinctive patterns
- Educational Value: Demonstrates mineral formation in copper-rich environments, characteristic banding caused by changing chemical conditions, and the use of malachite in carving and ornamentation
This malachite sphere highlights both the natural beauty and scientific significance of a mineral long valued for its striking patterns and copper-rich composition.
