Tektites?

1)I would risk assuming that the first two stones in your photo are the same stones as in my first post and these are the same as the long stones. The ones that are light inside, the ones that I called silt. And they do not look like this stone of mine, which I compare with your photo of indochinite.
It's very interesting to see what's inside those first two stones from your last photo.

2)and the stone that I compare with the photo from the wiki about Darwin glass - to me it is sooooo similar.

the bottom stone in this group of photos has a similarity in shape to your first two stones from the last photo. and my stones are all the same. and this is the group of the first post and the long ones.
but on my face these pits are less pronounced and smoother..
