Hi Alex and welcome your rock looks interesting especially the inside, put more pics up and close up of the inside and make sure pics are clear also give us some details, i.e. attracted to magnet, weight, streak, visible metal, your rock look like it has shock fractures inside but need close up and the arse end looks bit ordinary rock but rest look cool, so details and clear close pics please, I'm learning myself but there are people here who know what they're talking about, good luck
