I found Coffee Bean Rock while visitng my favorite coffee place (Centrally Grown, in Cambria). I wandered down the hill from the store to get a better watch on the ocean's activity: swarms of birds feeding in one area. I found a metal plate to sit on and watched awhile, enjoying my coffee and rosemary olive oil baguette. I looked down and found this beautiful stone - dark, smooth, a bit of line from another material: just like I like them.
Kind of looks like a bean. Measures approx 2 1/2" long and is rather flat.
