Tree Agate, also known as Dendritic Agate or Moss Agate, is an opaque Chalcedony Quartz. Dendritic inclusions make it appear to have distinctive mossy or tree-like markings. The tree-like markings are called called dendrites, a name derived from "dendron", the Greek word for "tree". The ancient Greeks noted Tree Agate as a stone of abundance and would sow some into their fields to ensure a good and plentiful harvest.
This piece is now available in my Etsy shop. I'll be adding several new tree agate pieces in the next few days. Thanks for looking.
