Had posted this one elsewhere but it seems to fit here also, a lot of things in the Tiffany stone nodule that is 7x5cm. Fun to see all the images that look like something we recognize. Kind of seeing the animals and faces in clouds.

The caption reads:

"I laugh when I look at it the Feldspar looks like a face and it has a Titanite Beard and Mustache I call it Sphene the Titanite King"

Don't worry, be happy.

While studying late one night for my paramedic course I glanced beside me and saw this face about 3 cm tall looking at me out of a marble bookend.

These phenomena--forms or figures in rocks or minerals that resemble other familiar (usually living) things--are known as mimetoliths. See Roland Dietrich's web page http://stoneplus.cst.cmich.edu/mimetoliths/ for lots of cool examples, discussion, and references.

And here's a muscovite "pig", 6.4 cm, complete with little tourmaline eye, exactly as found at the Helen Beryl Mine (Sweepstakes Beryl; Big Tom claim; Kem claim), Fourmile, Custer Mining District, Custer Co., South Dakota, USA in 1987.

A specimen of sfalerite from Lauthental, Harz, that is happy to be in Mindat.
