Green mineral, maybe microline?

[fuss]

This was part of the collection I bought, no labels info etc.. It streaks white, hardness of around 5.5 and is not brittle. It does not look like a feldspar to me but all I can think of is Amazonite variety microline. Thx.

I don't have a clue, but it's a nice specimen!

With that color and lack of cleavage it could be rough turquoise.

Could be chrysoprase, looks like a silicate. Just my 2 cents.

Good call smokey, I did not consider Turquoise and the hardness, opacity and luster match up.

I considered chrysoprase as well digginthe1, but too many things went against the idea including opacity, hardness and color.

I was guessing, but I'd keep it just as is! It's really nice.

Definitely Variscite. I'd say the possibility of it being either chrysoprase or turquoise is slim

That sure does seem right to me now. Thx.

The color is right for amazonite. Amazonite gets more bleached color closer to the surface. I mined some in CO. awhile back and it was not very deep. The color is close. Hardness close, streak is right.

This isn't a great example of amazonite as it was made for the ring. This was near surface found.
