Moving around the different show locations, one can see that the economy slow down is having a visible impact on the rock business. It seems that both the number of visitors and exhibitors are facing some shrinking effect.  Several dealers complain about the reduced cash flow. But this can also be an opportunity...anyway some dealers performed very well, selling most of their stock. Here we have some shots showing some new minerals and some good classics.

Gemmy crystals of Scapolite came out from Kurur, Tamilnadu, India. Just a few were seen around, but they are really nice, with individuals as big as a finger and with a good termination. They resembled some old Tanzania or Switzerland samples. The crystals have no matrix and could come from a weathered  marble. No analysis available yet to check if they are closer to a Marialite or to a Meionite composition.

 

The uncommon sulphate coquimbite was found in unusually well developed  crystals in the Javier Mine (Ayacucho Dept., Peru). There are discussions about the origin of this occurrence that could be related to sulphide oxidation or according to other opinion to very low grade hydrothermal mineralization. In any case the specimens are attractive, especially under natural light, and have a nice lavender color. The association is with metavoltine, alunogen, halotrichite, krausite, jarosite and chalcanthite. Those samples cannot be washed in water and the preservation will be easier in a plastic box, but dealer claims that they are unusually stable. In any case, they are very well representative for the specie.

 

A still unveiled and secluded Namibia locality produced very good Phlogopite crystals in a carbonate matrix. The Phlogopite individuals are well developed, generally isolated or forming small groups and range in size from one cm to 7-8 cm. As in the mineral world most of the secrets are not long-lasting, we will probably hear again about those samples.

 

Interesting tourmaline (likely Elbaite) was on exhibit at Quality Inn where many Chinese and Russian dealers  are present. Interestingly, those sample show both poles terminations on the same side of the cavity where they were found. This is quite uncommon, as most of the localities yielded just "flat" or "faceted" terminations. The color is also different, with flat end light blue and the other raspberry red (left). On the right a nice beautiful Brazilian sample from Paderneira Mine.

 

Beautiful orpiment samples are coming from Peru. The association is quite interesting, with tabular barite and prismatic Realgar crystals. Properly handled these are no-damage aesthetic samples. 

 

New dark bluish garnets (?) from Pakistan where seen in El Pueblo dealers area. Some more samples and info might come in future.

 

Carrolite source (Kamoya South II Mine in  Katanga, Democratic Republic of Congo) did not dry up yet: here is a giant crystal on matrix, available with many smaller others at La Quinta area.

 

Wulfenite from Mobile Mine, Clark Co., Nevada. Several specimens were available, and the quality is good.

 

Nice material from Dalnegorsk: a Pyrrothite "killer" brought by the top class Russian dealer Mr. Panomarenko and some more common siderite spheres.

 

Impressive pink Apatite came from the classic Himalaya  pegmatite mine. Some exceptional groups of cavity were discovered, but detailed info seem not to have spread yet. There are both crystals in association with muscovite and others with feldspar. Beautiful.

 

India deposits still produce huge amounts of zeolite: here some examples of recently collected Mesolite samples

 

Three top call classical US specimens: Cd-rich Smithsonite  from Arkansas, Rhodocrosite from Colorado and Benitoite & Neptunite from California.
