[curious kat]

Found this "green" (no, not obsidian ) along with the agates that I found in front property yesterday, anyone know what it is?

They are all quartz types

The green part is also quartz? First time I've seen it like that here.

Do a hardness test on that green stuff, it doesn't look lite quartz to me. I'm not sure what it might be though.

 

[curious kat]

OK EU....so that would be...hitting it with a hammer? lol .....how would you suggest doing that please? It doesn't scratch off with my finger nail, does that count?

 

[curious kat]

Another view of the "green taco rock" lol ....

Are you sure the 'green' is rock? Might be some copper deposit.

Hitting it with a hammer is a test of cleavage and/or fracture not hardness.
Your fingernail has a hardness of 2.5.
How thick is the green layer?
Chaldedony can be green but it is not common.
Are there any copper deposites in your area. You find lots of green rocks.

looks to me like you may have some agate-the smaller ones anyway. they will be harder than the quartz. look to see if there is any fire in the agates.

 

[curious kat]

It's very hard, don't think copper deposit is hard?

 

[curious kat]

Very nice site EU, thanks!

 

[curious kat]

I took a look at the great site EU posted and tested the hardness with a knife, couldn't seem to really scratch it with that, seems pretty hard. The thickness? Can't really tell other than what it looks like, sort of thick. Haven't seen any copper around here, but that doesn't mean there isn't any. First time I've seen this type of "green" rock here.

 

[curious kat]

We do have fire agates here Marinedad, but not in this rock. Looks like crystal in there. Here's the pic. of my fire agate.....

I guess without letting someone knowledgeable see it in person we might not get a proper ID here.

 

[curious kat]

Yes EU, think you're right, but that's alright....it can stay just an "odd stone", I'll still enjoy it ....and thank you for trying to help

There is a variety of green quartz called aventurine, just a WAG.

 

[curious kat]

Maybe it is? Thanks nomad will check it out. Have a nice Thanksgiving tomorrow!

Nomad1 is correct. It's aventurine. Great find

Gee....thanks Brian.....guess we can mark this one "solved"! I'll have to research it later, have a nice Thanksgiving
