Silver Needle Needle Agate
Silver Needle Agate is a Sagenite Agate which is known for its needle-like crystal formation. Colorful translucent to transparent beads often show a natural blend of varying shades of green, brown, creamy white, salmon, and golden yellows in intricate random patterns. Each natural stone is unique, and some are cut to be as delicate as fine transparent crystal—which is evidenced by the remarkable sprays of the needle-like crystal inclusions, which gave rise to the name of this beautiful Agate. Like all Agates, there are varying degrees of opacity in most stones, adding to the beautiful patterns and colors. The subtle shifts of colorations and jagged streaks of the crystal formations are mesmerizing in the sunlight! Sagenitic Agates are found all over the world in most agate deposits. although the occurrence of Sagenite inclusions in agate is usually limited. The crystal like Inclusions occur where iron oxide, manganese oxide, or other oxides are present when the agate is formed. 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.
