Is this potentially a meteorite? Dont look at the blue/green colours they are all reflections. Real colour is silver

[QUOTE="user 4386, post: 643061, member: 4386"] Terry, getting a vote on identification is meaningless when we don't know the properties. I asked if it was magnetic, its hardness (a couple of times) and also if I was correct that there was another light mineral present (#3,6 &10 above). Colour is pretty meaningless, appearance in a photo is usually meaningless - yet that is all that you have provided (my only comment would be that the cleavage, colour and lustre all make hornblende or galena a bit unlikely although they are intelligent gueses). For example, if it is magnetic it will pick up a steel needle (if not magnetite it is not a meteorite for other reasons of its appearance). A "gold" coin and certainly a needle will scratch sphalerite but not magnetite. Quartz will scratch magnetite. It is dead simple to do these things - it is almost certain that a vote will be of no real help whatsoever as people can only guess without any diagnostic info (although if I had to I would guess that it is not a meteorite - but that is still my unreliable guess despite half a century as a mineralogist including working with meteorites - if I am unsure I doubt if many other people can be reliably sure).
