A distinctive variety of orbicular chalcedony found exclusively along the coastline of Madagascar. The crystal is characterized by its spherical patterns, which formed when silica-rich solutions moved through cavities in volcanic rock over geological time periods.
The mineral displays a range of colours including greens, pinks, blues, and whites, often with small druzy quartz crystal formations scattered across the surface. These circular and flowing patterns are created by rhythmic chemical precipitation, resulting in the crystal's signature "orb" appearance.
The original Ocean Jasper deposit was located in a coastal area that becomes inaccessible during high tide, making extraction challenging and limited. This has contributed to the crystal's scarcity in the market. The material typically takes a high polish, revealing the internal structures and colour variations clearly.
Each crystal shows unique patterning due to the variable conditions during formation and represents a specific geological formation that captures the intersection of volcanic activity and silica mineralization processes characteristic of Madagascar's unique geological history.
