Thanks for sharing. Reminds me I have some rocks from a tin mine. Nothing spectacular, but found rocks always have a story and a precise location to them that bought rocks can never have, even if hard to find truly amazing samples.
Maybe just been unlucky with recent locations. Can see the kinds of elements around but just not blended together properly!
I understand how it is with rock collecting. Sometimes you find really good ones, and a lot of the times you don't.
