Tree Agate is a beautiful stone which resembles foliage. It is a type of dendritic agate, this crystal contains green dendritic inclusions. The inclusions look like tiny tree branches or foliage throughout the white base of the stone.
This set also contains a blank rune (additional stone with no stave carved on) also known as Odin's rune or the Wyrd rune - this is a modern day addition which some people prefer. If you prefer to stay with the more traditional feel of rune casting you can omit this stone from your castings. Use your own intuition as to if you would like to keep the blank rune in your set, enjoy your journey!
