May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Rusty, thanks for your input. If I had a better macro camera you would be able to see the copper.

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Thanks Alfredo, I will try that when I get the opportunity. My neighbor seems to have misplaced his metal detector.
May 2010Re: Copper included QuartzReply from Richard Felicioni in General.If you agree that the inclusion is copper, wouldn't it make more sense for the red coating to be Cuprite (Copper Oxide) than Hematite (Iron Oxide)?
May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Here's two more photos in sunlight.
I feel kinda stupid for thinking there was a fluorescence going on in this specimen, but I am still amazed how different it looks when viewed in different lighting. If anyone would like me to try something different with this Quartz please let me know. Thanks ...

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Debbie, I did a quick google search on "Cuprite in Africa" and I found the "Field Guide to Rocks & Minerals of Southern Africa by Bruce Cairncross".

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.As Ron said no change after light exposure. I must of changed viewing angle or how close I held to the light or something. The photos this morning show no change.
May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Thanks Debbie for the info. Looks like I have some work to do.

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Paul, I don't mind you doubting.

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Thanks Rob and Jasun, I am going to try to photograph the specimen to determine if there is anything more than just reflection going on.

3. Photo the Quartz immediately after removing it ...
May 2010Re: Copper included QuartzReply from Richard Felicioni in General.This specimen is from Messina Mine in South Africa. The description also states there is Cuprite included in the quartz, maybe this is adding to the coloring effect I am seeing.

May 2010Re: Copper included QuartzReply from Richard Felicioni in General.Thanks, the quartz is copper included, you can see copper pieces in the quartz. But your answer got me thinking that the light is reflecting off the copper giving the quartz the appearance of being coppery orange colored. I am not sure why when I first put it under the light the quartz appears ...
May 2010Copper included QuartzPosted by Richard Felicioni in General.I have a piece of quartz which is copper included, the quartz turns coppery orange when under light. When the light source is removed it fades back to clear. Does this mean the Quartz is fluorescent? If so, is it the copper that is causing the fluorescence?
Any input is appreciated.
