So what is Dendritic Agate and how is it formed?

Dendritic Agate is a part of the agate family (hence the name). Agates are an extremely common rock formation, consisting of both chalcedony and quartz as their primary elements. Dendritic Agate’s name is a bit of a misnomer, Agates are generally classified as a microcrystalline form of quartz with specimens showcasing bands of alternating colours, whereas Dendritic Agate does not contain these bands but instead very beautiful fissures. Dendritic Agate is closer to a Chalcedony in its make up which is also a crystalline structure, however, it consists of a fibrous crystalline structure. Chalcedony’s tend to appear milk, translucent or opaque.

Dendritic agates form when water, rich in manganese and iron oxides, flows through fissures and cracks in rocks/minerals. Sometimes, this water can seep into the three-dimensional crystal structure and develop incredibly detailed formations. As water containing these oxides enters the crystal structure the black/brown particles of manganese/iron are left behind. The unique branch patterns require millions of years to be formed and only the right conditions allow the solidification and crystallisation of the particle.

Where is Dendritic Agate found?

Most Dendritic agates tend to be found in Brazil, however other deposits include India, Iceland, Mexico, the USA, Kazakhstan and Madagascar.
