Streak is reddish brown. Iron nail can scratch it. It scratches glass. It is weakly magnetic. Has small steel gray crystals which are opaque and some of them are in rectangular shape. Doesn't react with lemon juice.

I think you have a piece of granite with iron inclusions.

Iron cannot scratch glass and can scratch your sample. But your sample can scratch glass. Doesn't seem to make sense unless the sample is a soft conglomerate of hard pieces.

Sorry, iron nail can't scratch it. I have found out that it is Ophiolite.
