Identity HelpHauyne or glass?

12th Nov 2019 14:22 UTCMees Bertens

An oil slick is occurring in this stone.
It has a density of 2.5.
And it weighs 10 grams
I don't know its origin.

And it's either glass (But it think it is to weirdly shaped for that) of Hauyne (But it would be too lucky) Any idea?

Mees,  I think I see bubbles in it, and if they are, it is glass.  The color is intense and seeing inclusions is difficult.  Hauyne has six directions of distinct cleavage, and I don't see any.  Further it is rather rounded at the edges, as if it had been molten.   Altogether, I think you have a pretty piece of glass.

I see the bubbles too. Best visible lower left. So Don is right, you have a piece of glass.

Agree, this appears to be glass.
The odd shape is likely due to water erosion.
