This intriguing semi precious gemstone material from India, is also known as Elephant Jasper, Elephant Skin Jasper, Cobra Stone, Calligraphy Stone, Script Stone, and probably a few others I haven't heard! But we like Coquina Jasper best because it is more accurate. "Coquina" is the Spanish word for cockleshells or shellfish.
Coquina Jasper is a consolidated sedimentary rock mainly composed of the mineral calcite, but usually includes bits of seashells or coral. Coquina Jasper forms near the shore, where wave action is vigorous and tiny shells and coral pieces landed.
