Hi, can anybody help identify this? Its diameter is around 1 inch (2,5 cm). Thanks!
It's my first time, sorry. In case the pics dont open up, you can see them here: http://s16.postimg.org/y7114l8o5/20140622_165528.jpg , http://s16.postimg.org/cw3h0bqjp/20140622_165542.jpg , http://s16.postimg.org/hlteoxhk5/20140622_165555.jpg , http://s16.postimg.org/v1gfedq1x/20140622_165627.jpg
Where did you find it?
It appears to be a geode of some sort.
Thanks for your answer. I live in Belgium. I found it like this in the garden
Looks like blue chalcedonny.
Thanks a lot Renata! It is indeed blue in daylight, so you could be right. Thanks for the comment
