I found this in a riverbed near Bathurst, NSW, Australia. It has a section where it is really clear through to the other side. Obvious rainbow inclusions - does it look familiar to anyone? Scratch test is inconclusive as quartz will make a white mark on it but when I sweep it away there’s no actual scratch on the surface, as far as I can make out. I may not be doing it properly though.

Looks like a water-worn quartz pebble.

The Rainbow inclusions are fractures that are extremely narrow and split the light up into its spectrum.
