the green ones we are sure that is serpentine, Not jade not nephrite, It is typical serpentine style. You are easy to see the white clouds inside.

I'm with you on that,love any gel to carve.All we have around here worth carving/cutting is antigorite from the serpentine barrens...That's what your stones remind me of, antigorite .It's called serpentine/jade around here by the lapidaries,it's harder than serpentine. Do you find your stone in conjunction with chromium deposits?

I think u re right, just hardness of this mineral is between 5-5.5. It`s maybe bowenite or something, IDK yet.

Ask John White what he thinks. I'm betting you have antigorite...first picture you posted of it in front of the ruler looked very translucent,almost transparent...Think you get to name it if you are the one who found it first... What comes from around here is called Williamsite...Again ask John White about this...I'm just a lapidary with mineral interest... :)

the one and only dark green serpentine sample from Mihail I had analysed was a hard variety (hardness 5 or 5.5) but it was not a chromian variety: there was no chelsea filter reaction, and there were no absorption lines in the red to be seen through a handheld diffraction grating spectroscope.
