Welcome Tammy, nice find!

Do you have any pics with the crust still on? Is a magnet attracted to it?

Best wishes and Happy Holidays?

I’m still learning so excuse all my extra pictures lol! Merry Christmas!������

what made you chip away at the crust? why did you think there would be something inside?

 

[Tammy Andress]

We saw someone’s post online awhile back showing how to chip away, they also said it was agate but as we see it’s not. We have a few more just haven’t had time to do them. I’ll post them when we do.

nephrite jade? I really dont know, it kind of looks like it has a petosky stone sorta pattern, faint spots. Its gorgeous whatever it is. Did you polish/tumble it?

Hi Tammy,

You might want to repost this in the Geological Forum http://www.treasurenet.com/forums/rocks-gems/

These folks will know what you've got.

I have one almost identical but of a smaller size, a dark bluish-black and in the shape of a plum, it turned out to be Basalt.
Basalt is a common gray to black volcanic rock. It is usually fine-grained due to rapid cooling of lava on the Earth's surface.
Maybe yours is Basalt also....
