The oval flower garden agate cab has a white fortification agate in the center. A fortification agate is named for the pattern that would be seen on the ground if one were looking down from above upon an old-fashioned fortress—think Fort Ticonderoga. (See Gemstones of the World, by Walter Schumann, page 134, 1977 edition, for discussion and photos of the fortification agate.) The point of this blog, beyond the beauty of these flower garden agates, is that it is very complicated and difficult to exactly identify a particular type of agate, particularly when many agates contain within them several identifiable specific types of agate. Ergo, this is a flower garden agate with a fortification agate in it.
