Bedrock Bob 3,885 Posted April 19, 2019 Share Posted April 19, 2019 It is a silicate mineral. Probably agate or opal because of the translucence and inclusions. Minerals are identified by physical characteristics and not so much by appearance. Stuff like hardness, density, fracture, streak, etc. etc. Photos only get you so far. It is some form of silicon dioxide. I'm going to call it an agate. Agates are a bit harder and a lot tougher than common opal so they round up nicely and chip less. This one looks like it is pretty durable and not prone to flaking and fracturing judging by it's fat, blobby shape. That (to me) indicates it is probably agate. Just a guess though. 1 Quote Link to post Share on other sites
