Is this a stone? It scratches tempered glass

Looks like a chunk of cobalt blue glass to me. I'm not aware of any blue obsidian.

It's likely a stone of some sort. It appears harder than glass

This is the rare and formerly unknown to exist on earth dilithium crystalline

Or it could be dangerous

It sure is a beautiful blue!

Just a bit of advice concerning what you wrote in your title...

I would highly advise not trying to scratch "tempered glass", tempered glass can and many times will shatter simply by just "scratching" it.

If you must scratch glass to do a hardness test make sure it regular glass and not tempered!

It's harder than glass but everyone thinks it's glass because of the clarity

So it could just be a harder glass than what you were scratching. For example if it was a borosilicate glass it would scratch a soda lime based glass.

I can say with absolute certainty this is not a stone. As in a rock. There is a sub section of geological science 'petrology' that is about rocks. You really meant 'mineral'.... amIrite? Rocks are made of minerals and minerals are made of chemicals (plural) -- with a exceptions like diamond that has only one chemical constituent.

So is it a mineral? It manifests the fracture patterns of glass. The man made ( mostly ) form of SiO2 which occurs in nature in minerals and rocks as various permutations of quarts depending on contaminants which influence characteristics such as color, opacity structure ... whatever. There are many many many forms.

If it is a mineral it is a mineral with a glass like structure. Obsidian does that. Gem minerals, on the other hand, usually manifest crystalline structures like particular atomic lattice alignments, fracture planes , growth faces...facets ... all that sort of thing.

Will you be coming back to tell us about how you acquired this? What do you know about it?

Thank you for the distinction. It appears to be potentially volcanic glass or some of the montana sapphires are this hue and appear as glass as well. I found it an an area of arizona where there are other artifacts around. In the desert of this area the native tribes would trade from all over. There is blue obsidian found in this area from the sanfrancisco volcanic field. Also not ruling out a possibility of montana sapphire as the more research I have done the raw sapphires with clarity look like glass structure. It's probably slag glass that ended up in an area with other artifacts so yes more critical analysis is necessary to identify.

Take it somewhere to be analyzed, then you won't be left guessing
