okayy, thanks for your time sir, I'll keep digging and searching some more ^^ have a good night

I did some more experimenting and broke a little glass kinda thing off one of it's edges. It looked like it didn't belong to the black stone.

I tried scratching it with a piece of glass and it didn't work, So I tried the opposite and scratched the piece of glass with the stone and it got well damaged and scratched.

I did and I can't even scratch it

how can I come to a final result ??

I don't think a melted wine bottle would weight 3.KG

How can I make sure this is agate ?

this stone was found in the sea, it doesn't attract magnets and it shines yellow when exposed to light. I tought it maybe an obsidian stone but I'm not sure... would appreciate any help and support ^^
