[QUOTE="user 4386, post: 660840, member: 4386"] Thanks. People can waste a lot of time and make incorrect identifications looking for differences that don't exist. I'm happy to increase their chances of success. For those who might be interested, beautifully transparent (and coloured) quartz occurs in a few places in many states (eg in the Wedderburn and Strathbogie Ranges in Victoria), but is not widespread anywhere despite the widespread presence of quartz in gold deposits. The typical vein quartz of gold deposits is full of defects and fluid inclusions that make it look white (it is not actually white). Transparent quartz in such gold-quartz veins is usually confined to individual crystals that grow into open cavities in such veins. So not a good source of transparent quartz in adjacent streams. Transparent quartz is more common in granite areas (such as those mentioned above in Victoria), especially granite areas that have pegmatite veins - in fact most quartz can be transparent in areas of pegmatites..
