Physical properties
Hardness of 6.5-7 on the Mohs scale. Colors primarily include whites, grays, and yellows in this specimen, but can have greens, pinks, and browns. Waxy to vitreous luster. Microcrystalline structure with orbicular (circular) patterns.
Formation & geological history
Formed as a rhyolitic igneous rock containing quartz and feldspar that crystallized into orbicular shapes. It is famously found in Madagascar.
Uses & applications
Predominantly used for ornamental jewelry, cabochons, and as a collector's stone due to its unique patterns.
Geological facts
True Ocean Jasper is known to come only from specific locations in Madagascar, making it highly prized among lapidary enthusiasts. The orbicular patterns are what define its appeal.
Field identification & locations
Identify by its distinct circular 'orb' patterns and smooth, waxy feel when polished. Very unique to its specific geological deposits.
