I have been in Tucson since last Sat and have seen a lot of minerals, including those of our excellent host Jordi. Attached below are some photos of stuff I have bought. Please excuse the photos - they were done in the bathroom of my room at the El Conquistador.
Considering that i am enjoying an adult beverage at present, you should be aware that the order of my posting is seen here from the bottom to top. As I am sure many of you have found out when posting pictures here, this website puts the first photo you post at the end of your posting. It is hard for me to put my pictures up in reverse order so please bear with me.
Regarding the Volodarsk-Volynskii "aquamarine," I showed it to one of the contributors to the minrec article last December and he told me that it may not have been heat treated because of the color. He said that the although aqua from this locality is very rare, it does occur. The material from this locality all started out aquamarine but then slowly turned to heliodor with natural irradiation. The miners in this area will take material with poor heliodor color and heat it up to 300C to turn it back into aquamarine, and this material is typically a deeper blue. i am not trying to say that my piece is true aquamarine. I don't know. In any case, I consider the set to be interesting and fun because they look cool together, one of them may be a real aqua, and even if it isn't it shows what the material looked like before it was irradiated by mother nature.

| Next up is a Mundo Nuevo Hubnerite I got from the same fellow who has the fluorites. The largest Hubnerite is 3.5 x 2.8 cm and the whole piece is 11 x 10 cm. The xtals are fairly lustrous, and all are terminated and all but one is complete. The bottom (not pictured) is a cast of several fluorites that have dissolved away. |

| Next up is a Mundo Nuevo Fluorite. This almost colorless grouping of complicated octahedrons formed around a quartz xtal that gets lost in the center of the piece. |

| Next up is Paprok tourmaline that I was drawn to because it has fantastic luster and is absolutely pristine above the bottom terminations. The largest xtal is 8.8 cm high. I asked Jeff Scoville to photo this one (I don't have his photo yet), |

| A "matched pair" of beryls from Volodarsk-Volynskii. The aqua is 6.7 cm high and is a pale blue (blue-er than the photo but pale enough that it may not have been heat treated). The heliodor is 6.2 cm high and was in the John Barlow collection. |

Last up is another of the Mundo Nuevo fluorites, this time a cluster made almost exclusively of two octahedrons with a pale but distinct green color. The bottom of the piece is broken but above that all the fluorite is pristine. The dealer said that this piece has the most saturated green color he has seen from the locality. It is 12 x 10 cm.
