What is this green stuff?! Join me for a mineral identification challenge!

I received some samples of a beautiful green material from one of my viewers (Thanks for the challenge, Sam!) asking for help in identifying what it could be. Join me as I test and use various properties of the material to help me narrow down the possibilities!
Findings:
Hardness - 7
Fracture - Conchoidal
Luster - Waxy
Streak - Too hard to streak
Color - Deep forest green with some blue, white weathering rind present on one sample
Specific gravity - mass of sample in grams/mass of water displaced by sample in cm cubed, divided by the density of water at 4 degrees C - 2.59

I first noticed the deep green and then conchoidal fractures. I was guessing maybe jasper. This was very cool and very informative to see you use 5 steps to identify the substance. I was unaware petrified wood could look that way. I had heard of green chalcedony. You have some amazing rocks and minerals and jewelry as well, that you show for comparison. Thanks for posting this great, helpful video 😁👍

Thorough and interesting. Beautiful color in those rocks. It also helps to know the local of collection, I think.

Great presentation! Thank you very much!

Being a flintknapper, if I saw this material lying on the surface, I would call it a really good quality chert, and I would look for and hoard all I could find! This stuff would make some beautiful projectile points and paleo knives. Beautiful, beautiful lithic material, makes me drool. Lol

Brilliant vid, Thanks. Would love to see the process for measuring specific gravity.

I will like to thank you for the full identification process for these stones. This can now be useful in my rock searches.

Waw.. nice videos, idetification gems with moch scale

[@MichaelJohnson-mo4em]

Thank you. Very good presentation and explanation of how to look at a sample. A gorgeous sample at that. The video quality was so good i could see the dust plume from the scratch when you used the 8.

I am glad CZcams has recommended this to me! I am going to subscribe to see more. How interesting!

Looks like banded green obsidian to me. I've snapped a few arrowheads out green obsidian.

Thanks for the very interesting video... awesome explanation!

[@truckerenoch8824]

Ive seen 2 similar to this. Chert from Wyoming, or flint from Texas.
