When the microcrystalline silica lapidary material we know as jasper formed so there are included needle-like crystals of different minerals in a radial structure, it is called Orbicular Jasper. Probably the most popular variety is Ocean Jasper. The tale behind this beautiful stone, as told to me by a geologist years ago, is quite amazing. In the early 1900s, it seems that pieces of this stone had been found along a beach in Madagascar and made their way to market only occasionally. The actual source was unknown and when it was sought, it was to impossible to find! A cartographer was hired to make a map of the Madagascar coastline and when the plane he was flying in was very low, he saw outcrops of an unusual rock in the water during low tide. When he went to the location on land, he no longer could see the rocks because the tide was high. Speaking with local fishermen, he hired one with a boat. When the tide was low again they made their way out to chip specimens of this rock to properly identify it.
