Here are a few new fluorite pieces in the collection. Locality details on the last two pieces are sketchy, but I'm confident that more specific information will eventually be revealed. The 2nd piece was reportedly found during construction of a high-speed railroad tunnel in 2014, but the language barrier prevented me from finding out much more about the location.

Michael,
the galenite from the Fletcher Mine is very aesthetic in my eyes.

Thank you for your comments Martin and Bob. BTW Bob, that quartz was purchased this year in Tucson for under $10, which goes to show that if you are willing to work hard, there are still bargains to be had.

Thanks Bob. The face shown in the picture is one of the 3 trigonal faces which is greatly enlarged. The other two faces are reduced to almost nothing. Very strange.

Thanks Bob. Believe me, I looked at a lot of plumbogummites before I found one without damage.
