Draggletail Posted May 26, 2012 Share Posted May 26, 2012 When I was a young lad I used to go digging around in the garden and yard like kids did back then (no Playstation in those days) Quite often I'd find what I called 'Lucky Stones' - they were a light olive greenish colour, and rough, but where they'd been broken they had a smooth and glass like surface. Here you could see swirls or streaks of another colour, usually green or black I think.... As stated above they often appeared to be broken, but it's really hard to imagine what could break these tough, dense things, not us kids anyway. They were about 3 inch in size, and this was in West Yorkshire. Any help appreciated Link to comment Share on other sites More sharing options...

The search results put me in mind of the stuff I used to dig up, but nothing is identical. There again there seem to be so many sorts of Olivine! The stuff I found was glassy and opaque. In the search I came across Olivine Sand for Foundry and I remember the sub surface of the yard was a sort of black gravelly slag, maybe a foundry bi product, so maybe the 'lucky stones' got mixed in with that...

Glassy and opaque, any chance it could be glass Link to comment Share on other sites More sharing options...
