Rock 166 ~ Treasure Among the Buttons ~ January 4 2016 ~ Pomona CA

I bought a large jar of buttons from a favorite antique store yesterday. I always look at the jars for sale to see if I recognize any treasures in the button mix. This jar seemed promising. I sorted them last night -- what fun it was! I found some Colt manufactured buttons (yes,the Gun Company), some Bakelite, and some non-button items...including this polished stone!
Measures approximately 1".
