Pretty blade but what material?

[Out Of Time]

Here's a broken blade I recently found in a creek in Northern California. Unusual material - is it chert? If so, what type?

Thanks for looking

Almost looks like a shade of green, is it?

burns green obsidian?

It's a pale green waxy material.
I didn't think it was an obsidian as it doesn't have a glassy feel or sheen.
But I just googled Burns Green obsidian (thanks Jon Stewart) and I saw examples of very similar colour.
Still, the texture seems off and the nearest source is in Oregon, as far as I can tell.

Not all obsidian is created equal and the Natives did travel about. Without looking at it first hand it is hard to tell.

It doesn't have to be Burns Green oBS, there are various sources of green from here to N. Cali.

It looks like Chrysoprase in the Quartz family found all over N. California all shades of green . This Martis Culture point is the same type of material found on the western slope of the sierras .

Hi there, I think you mentioned Chrysoprase before, now seeing that beautiful Martis point, I'm convinced my blade is the same. Thanks for solving the mystery.
