Could someone help me identify what this arrowhead is made of?

Question

I received these as gifts from a relative, so I don't really have any background information about them. I'm almost certain the small black arrowhead is made of obsidian. I have another arrowhead made of obsidian which I can reference and see the similarities. But I'm more focusing on the larger arrowhead. Maybe it's just made of a stone, but I'm still curious. Any help is appreciated.

Answer 1

John, it could be chert.

And I have seen a brown obsidian. Any hints as to where they were found? Could go a long way in identifying them.

Comments

Thank you for the suggestions. I honestly have no clue where they came from; my relative that gave them to me lives in Nevada and he must've bought them so maybe they were locally found and sold? I haven't really seen a mineral like that before, it's not just one solid color and it seems to have different layers.

John, chert is microcrystaline silica, a colored flint, sort of, agate, flint, jasper, chert and obsidian were used for arrowheads. They are particularly hard and subject to conchoidal fractures. The same waxy feeling you get from agate, you sometimes get in chert. The hints are conchoidal fractures and smoothness from the micocrystaline nature of flint, chert and similar silica based rock.
