Rock or Glass?

[HenryWaltonJonesJr]

Found this on our regular beach glass hunt, but is this Quartz? We find glass that looks melted or something else, but I'm thinking rock. What do you think?

I believe that the light Lime greenish colored stone in pics 1 thru 3 is probably Quartz but it sort of favors a cloudy, river/stream or wave action tumbled Peridot. The stuff in pic #4, I am sure you know and posted the pic to show that most of them are colored pieces of glass which have also been tumbled in the same manner.
