[QUOTE="Lefty, post: 445566, member: 2976"] Looks like waterworn smoky quartz, but you say it's too hard to be that? I was shown some brown topaz crystals while digging kn far north QLD - the colour of them would have had me saying they were smoky quartz but the un-weatherd crystal in its perfect original shape showed that they were indeed topaz. Interestngly, I believe that treated blue topaz is made that colour by first irradiatiing colourless topaz which turns brown in response. The brown topaz is then heated and turns intense blue.
