I found these rocks in San Juan County Colorado last month they are not Amazonite , or serpentine. Nor do I think they are Quartz. Thery are smooth to touch and I scraped them with a knife and it doesn’t leave a mark on them.
Hey all, found this in in a rock pool. It's not extremely heavy, or even light, has a gold/sliver shine to it. Leaves a grey streak. No idea... Any help. I'd appreciate.
