About three and a half inches high. Handrubbed beeswax finish. The stone seems to be onyx with an unusual configuration of black and white sections; I've had it for a long time and don't remember where I got it.
(I suspect it was at one of the San Francisco Gem & Mineral Society's Open House events.)
I love how all of your stuff looks so meaningful. Like each item may be similar to objects of that use, but is also unique. They always give me inspiration as a writer, be it for a character's cherished, though mundane possession, or some plot-relevant something of power and far-reaching recognizability.
