The dust you got from grinding, what colour was that? I think you may want to open it up with a hammer so we can see inside of it.

Hey, Eu c, kept some dust/powder (color is tannish/beige)..a few bits/pieces popped off too, will put pic of them here shortly. Re: hammer, i've knocked some chunks off too...same thing (rust exterior).

Limonite produces brownish streaks. Example: Streak plate test of the mineral Limonite - 42-23929347 - Rights Managed - Stock Photo - Corbis
Can you scratch it with a knife?

Hi Eu, yes the rust area leaves brown streak..but the polished green area leaves no color. Very sharp point of knife pressed down hard leaves a white line on the green area.

Thanks for the thought TM.

the stone appears to be copper slag...some iron residuals in the center

pwp, would copper slag have the jade green colored stone as the matrix?

 

[pippinwhitepaws]

perhaps...if exposed to water over time..
green, blue in some shade is evidence of copper...

The "white" line on the green stuff just means it was harder then the knife.

I don't see any way to resolve this other then that you should take it to a local expert.
