Department of Geology in CroatiaThanks! I tried to scratch it but it is too hard. I live in Croatia. This rock was found in a continental type of forest just on a pile of leaves during a walk with my dog. What else can I do to help with identification?
It's milky quartz, rather than a true quartzite.I found this nice looking rock in a forest nearby but want to be sure it is safe for my tort enclosure. Does anyone know what it is?

I have some lovely pieces of cinnabar in my collection here.Are there any rocks that are toxic to tortoises?
Omg. That's unreal. The only Rock I have that is dangerous for torts. Is the Blackpool type. . Thanks Adam. That is very interesting stuff.I have some lovely pieces of cinnabar in my collection here.
That is mercury ore and certainly toxic, even a little dangerous to handle.
Galena is fairly common and is a lead ore, also poisonous.
i have some radioactive meteorite pieces, i wouldn't recommend chewing.
Then there is arsenopyrite which contains arsenic and stibnite that contains antimony sulfide which can be lethal.
Not to mention various asbestos ores.
CINNABAR (the reddish bits are lethal.)

GALENA (the black cubic bits) Lead. Not good.
