Rock coin identification help

0 votes

Hi there!

I'm hoping you can help me identify the stone that this coin that I attached a picture of.
My first guess is lizardite, but not quite sure that is right.
The only thing I know is that this not a common stone.

Any help would be great!
Thanks!
Tim

The color and mottled nature would certainly agree with your designation of Lizardite, which is a type of serpentine. See if it has a greasy feel and a low hardness. There is some scapolite labelled as Wernerite with a similar color and pattern as this - you can test that by seeing if it fluoresces, even in longwave.
