Additional Information
The slab that made these cabs was from an unknown origin. They are similar to graveyard point agate. They are just another example of a plume agate with a somewhat different type of plume. The agate background has many small fortifications and a few small crystal pockets.

Cabochons cut by the author and are framed with black jade. The first and third cab are backed with black jade too.
