PostPosted: Jan 21, 2025 21:43    Post subject: It's Tucson Time Again - 2025  

The mineral world is starting to show up at the various venues in and around the mineral capitol of the world - specifically the Mineral City area of Tucson.

As has been tradition for many years now, the first vendors to arrive are the ones that need to travel the furthest. Adam Wright of the Adelaide Crocoite mine in Tasmania is once again first and then there's the intrepid South African Clive Quite again in his room in the "B2B annex" (previously the Top Gem annex - I encourage you all to read the emotional eulogy to Top Gem founder Mike New by his son Jason in last year's Min Record).

South African Paul Botha arrived to find one of his 8 ft tables collapsed into two four-foot tables taking lots of glass shelves and minerals with it. Frederic Gauthier of Little Big Stone (Madagascar) arrived and is waiting for his new shipment.

And one US dealer - Bruce Wood is fully functional at his Min City room full of nice material at reasonable prices.

I'll start this years Tucson thread with what has become tradition for many years with the recent Crocoite report from the Adelaide Mine, Tasmania.

Also - Please note that although i've started and populated this thread for the last many years - Please feel free to add to it with your experience at the shows - One guy can't possibly see everything.

It was a very good collecting season for Adam Wright in the world-famous Adelaide Crocoite Mine - pretty much the world's only source of display caliber crocoite.

Adam entered a zone that he calls the Red River Falls since the zone was literally a water fall when he first opened it - see last year's report for an in-situ video of the "falls".

The zone produced (and is still producing) what may be the best overall specimens he's ever collected - mainly thanks to the very large crystals encountered - up to 9-10cm!!! - that are also colorful, lustrous and nicely terminated - and did not require any chemical cleaning.

Some photos below - I apologize for my less than perfect photography - the specimens look much better in real life - the very best ones are already spoken for.

Clive Quite's room in the B2B Annex is not officially open yet, but visitors were permitted to stop by and say "Hi" - if you know what I mean.

Clive is still not in good enough shape to do something as demanding as the Tucson Show so his partner Tony is in charge with excellent support from Jose' and his wife Sofia.

In my short time there, I found a large hoard of Congo Dioptase and velvet malachite along with the usual flats of cactus quartzes - and a few special pieces. This HUGE Japan Law citrine is in remarkably great condition - the terminations are near perfect with only a few "Wilburs".

There was also this pseudomorph labeled as "Malachite after Chrysocolla" but I'm not so sure about that - an excellent piece though.

Still very few rooms are open right now - major move-in efforts are underway. So, I went back to Paul Botha's room, and he had recovered from the "8 ft Table collapse" and he is almost fully operational.

There are lots of black minerals in his room - shiny and very large pieces - some massive smokey quartzes from Mt Malosa and huge aegirines from Mulange, Malawi.

He also has some new, mineralogically interesting "polyhedroid" quartzes from Reimvasmaak - some contain "geode style" vugs and some are complete floaters. See photos.

More Congolese Malachite fun!

In a previous photo I showed what was labeled as Malachite after Chrysocolla - maybe - would love to hear other opinions.

Then - I found other interesting Congolese items in Clive's room:

First what is labeled "Azurite on Calcite with Second Generation Malachite". It's actually a very nice specimen - good color and luster - but does this sound correct? Maybe Azurite coated Calcite altered to Malachite?? - or maybe Malachite after Azurite after Calcite??

Then another labeled as "Malachite" - but it seems "Malachite after something" is more appropriate - maybe after selenite?

Finally, there's what is labeled "Kolwezite" but the crystal form and color look wrong - maybe it's malachite?

Anyway - other's thoughts are welcome.

IMG_2247 could be kolwezite after azurite - i have seen some that look kinda like this. But it looks more to me like malachite after azurite.

I found quite a few and interesting items in the Russian Stones room in the E-Building.

Alex and Vsevolod Chernousenko are diggers at the famous Ukrainian Heliodor locality and have a large selection to pick from.

See photos.

I purchased something years ago like your malachite that was from Zaire - no other locality info - that was called a pseudomorph after barite. It is more like your third specimen - platy and less prismatic but in sprays.

I visited Wendy Yuan of Wendy's Minerals and as usual she had some wonderful new items - especially the "Two Generation Fluorite" specimens that were etched out of enclosing quartz. The contrast between the two colors is excellent and some have very distinctive phantoms. See photos.

There was also a huge plate of 3-generations of fluorite flanked by two attractive plates of rhodochrosites from the Wutong Mine.

Lots of other terrific items to be found in her room.

With the inherent difficulties of deciding on something based solely on a photo and not having the piece in hand, here are my opinions:

I don’t think so. It looks like Malachite pseudomorphing Baryte or Azurite.

>Labeled "Azurite on Calcite with Second Generation Malachite". It's actually a very nice specimen - good color and luster - but does this sound correct? Maybe Azurite coated Calcite altered to Malachite?? - or maybe Malachite after Azurite after Calcite??
I think it’s simply ‘primary’ Malachite (not pseudomorphing anything, just crystallized Malachite)

>Labeled as "Malachite" - but it seems "Malachite after something" is more appropriate - maybe after selenite?
Indeed, it looks like Malachite pseudomorphing something. Perhaps Baryte, as it’s hard to imagine Gypsum being able to support until to be pseudomorphosed something like Malachite without losing its structure/form first.

>Labeled "Kolwezite" but the crystal form and color look wrong - maybe it's malachite?
Labeling this piece as Kolwezite seems overly ambitious. It looks entirely like Malachite crystals (primary malachite)
