Featured Black Stone Carved Frog Figurine

Any idea what is the stone, it changes color from black to whatever color that it.
Thanks

 

Try searching "golden sheen obsidian".
I had some jewelry that turned out to be that stone, long ago.
Your frog looks similar in the pics, so that's my guess.

 

I also think obsidian and likely from Mexico.

 

Gold sheen obsidian turtle.

 

Yep. The carving is dead on for Mexican too. They make this stuff for the tourists, and probably their own use too.

 

I searched and found my old pics from 2007.
The gold/golden sheen obsidian looks pitch black until under bright light, the golden sparklies appear.

My pics were under fluorescent light, which makes it look slightly greenish-gold.
