You can use the image upload icon to upload pictures. Its the 6th icon from the right side in the editor. We'll need to see some pictures to see if we can help you.

Jo, the picture is there now. That's Smoky Quartz - and that's a nicely sized piece with good color. Where did you find it? Are there more like it?

No, Herschel, just the one. I found it in a really incongruous place - in a grass clippings dump beside a town dam so dont know how it got there. It had been stormy so perhaps it was washed down the bank by the rain.
Usually when there is one there is more, I would suggest you look there again. Also, its possible it was transported from the dam construction and they used fill from a pegmatite vein. Maybe if you can provide some locality information I can see if there are any pegmatite quarries nearby with smoky quartz.
