probalitty for these three,crystals thank you.

 

[what]

The first one is probably quartz but the other pieces look like slag glass to me.

The last one looks like Libyan desert glass I have seen pictures of. Tectite?

 

[nass]

thank you niffler, what

 

[DDancer]

Libyan glass is a tektite, a glass formed by meteorite impacts. Sorry none of them appear to be tektites. All quartz : Upper left clear and milky quartz, upper right and lower left either smoky quartz or chalcedony, lower right chalcedony.

May I ask how and where you found these please?

I found them in a mountain, in a Roman village destroyed completely and abandoned, North Africa
