What stone is this?

0 votes

alt textI have been searching for 5 days now on the internet and asking friends but no one seems to know the name of this stone.

It is mica like, has small flakes and after a soft brushing, underneath the light green there are some greener spots. It also has some black spots. If I scratch it over a tile it gives a white mark. It becomes brittle in water and gives off flakes.

I have similar stones with a pinkish color.

Can you take a few more pictures? Also see if you can improve the lighting so we can see the photo better.

I hope these are better pictures.

I have in my collection fuchsite. I compared, but it is definitely not fuchsite. Or kunzite or cyanite. Nor lepidolite. Not amazonite.

I don't know where the stones come from. I bought a box full of different stones through the dutch equivalent of Craigs List.

I don't know why you are ruling out fuschite - its green and micaceous so that should definitley be a viable suggestion. It definitely looks like a mica. May also be chlorite but mica (probably muscovite) most likely. Why are some green and some peach or beige colored? Is that due to the photo, or different samples that you have?

Hi Hershel,

Yes, different colours but they all "feel" the same.

I'm ruling out fuchsite because I own a piece and can compare it directly. Fuchsite has an opaque characteristic, and these stones don't.

I was thinking muscovite myself but the 'flakes' are much smaller then muscovite.

I will have a look into chlorites.

Thanks for your answer.

Renata
