Nipomo Agate Cabochons
Pretty Nipomo Agate from Nipomo, California. Sometimes referred to as Marcasite Agate, these cabochons have golden metallic Marcasite and Pyrite inclusions. This material is pretty rare. The collecting areas have been closed for more than 40 years and old sources are getting scarce.
Agate is a member of the chalcedony family, or a microcrystalline quartz, and it has a hardness of about 7 on the Moh's scale. The name is derived from its occurrence at the Achates River in southwestern Sicily. Marcasite and Pyrite are both forms of iron sulfide. Marcasite and Pyrite can form in Agate during volcanic activity.
Metaphysical properties: In general Agates are said to be stabilizing and strengthening. They improve memory and increase energy.
