Dendritic Agate, Garnet, and Diamond Gold Ring
by Karin Luvaas Jewelry
Dendrites (Greek, meaning "tree-like"), in agates are formed when iron oxides or other minerals are deposited within quartz crystals as they form at a starting point and branch outward. As the water containing these oxides evaporates, the mineral particles are left behind creating the branchlike patterns (nature's watercolor!). Dendrites occur along deep cracks, down a flat, narrow plane between rock layers, causing the dendritic forms to grow flat alongside the planes of rock in which the water flowed (note, this doesn't happen overnight — it takes decades!).
