Tube Agate is when the inclusions are shaped like tubes. Metaphysical Properties: In general Agates are said to be stabilizing and strengthening. Wearing Agate cabochons is said to help improve memory and increase energy.

With Tube Agate formation, extremely thin mineral rods grow inside the silica gel before the gel solidifies and the chalcedony forms. Sometimes these rods remain as inclusions, while other times they hollow out and fill with silica. They are visible as tube-like formations inside the resulting agate.
