Hi. Is it possible to photograph these on a completely white background? This will allow features to stand out and in turn, accurate assessments to be made.

Smoky quartz for the chip and a pebble of milky quartz. The pebble could remotely be a topaz but I'd have to know if the area is known for topaz and then chip it or make a window to see the interior.
Volcanic glass? Never seen obsidian so clear. Hehh....
The fracture pattern looks like it may be glass. See if you can scratch a glass window (just a small scratch) if you can it is probably a variety of quartz crystal.
