Silver Needle Agate is a Sagenite agate, which is known for its needle like crystal formations.The “needles” or filaments intersect and are often arranged in fans or sunbursts. Sagenitic Agates are found all over the world in most agate deposits. Although the occurrence of Sagenite inclusions in agate is usually limited. It occurs in nodules or veins. The oxide minerals grow in the agate when it is in a liquid or gelatinous state. The inclusions grow and are supported by this liquid medium. If sageniteinclusions grow outside of the gel, the tops of the needles resemble a
pincushion. The pseudomorphous inclusions get their form mainly from needle-shaped acolytes. aragonite, gypsum, goethite and antimonite. Sometimes Sagenite and Plume (fluffy moss-like) inclusions can occur together.
