It definitely looks interesting. Can you please give some details on the locality as well as the environment you found it in? This may aid in identification. Were there any similar stones present? Also if you can post a few more photos that would be helpful.

I think there is a possibility this is lapis lazuli but more information would help.

and the area is all like this


area is full of water and streams and coppice..i hope i help atleast little bit :)
Thanks for the additional pictures. That material is definitely interesting and intriguing! There appears to be somewhat of an internal fibrous structure but solid composition, which may indicate crocodolite within chalcedony. Its definitely unique and worth testing. My advice would be to look around the entire area for more. See if you can find its origination or where it comes out of the bedrock. If you find more definitely send us some samples for testing.

Also, what is the locality you found this in? Perhaps the local geology of the region can give us some more clues.

I was searching for more samples but i couldnt find any..so maybe i can cut piece of this one which i have and send you. What do you say? I really wan't to know what is this thing. here is one more photo http://prntscr.com/7sn6nq  :) Regards Vinko
Vinko, thanks for the additional information. Another possibility may be opal. Is there any way you can test the hardness of the stone? If you want to take a small sample and send it to me, fill out the form at --- and i'll reply with my address
Ok i want to send a sample, but what form to fill? Can you give me link and i will send you that little piece.
