Since I am not a specimen collector, I tend to avoid shows that specialize in them, and have not ever taken Bonnie to the Westward Look Resort in the foothills north of town where the classiest specimens can be found. I have been there in the past and enjoyed it, so today that is where we went to look at the eye candy.

Westward look at the Westward Look Resort

Both foreign and domestic dealers are represented at this show. They advertise 40 dealers, many selling to museums and discriminating collectors worldwide. Each dealer has a room at the Resort and it looked at though purchases were being made, where we saw gaps in the cases and saw many conversations going on between knowledgeable people. We wandered from room to room looking at their beautiful specimen displays. The cases are illuminated professionally, with special true-color LED lights. Due to the number of photographs, I will divide this and give you more photos tomorrow. Each specimen is museum quality, and it was hard to choose favorites to take pictures of, with thousands of premiere specimens to see. I did not note who each of the owners were, but hope you enjoy seeing the photos.

Tucson Gem Shows-JGX

75 and gusty

steampunkwaterbuffalo

Steam-punked Water Buffalo was very bizarre.

amethystpieces

We began today at an interesting smaller show, the Jewelry, Gem & Mineral Exposition (JGX in the tent you can see from the Interstate) on Simpson Street. Parking is good there, and the crowds are not as thick, there on the weekend, like some other shows. We recommend this show if you have walking issues or handicap issues and want to participate in the gem shows. They have a variety of products here, solid parking, a firm floor, smaller crowds, open to the public, and not such a huge venue.

A couple of dealers there always get some of our interest.

opals

Very fine Yowah Opal.

 

Jeff and Kerry Chappell sell the most beautiful Yowah Opals which they mine and process in Australia. This booth is a marvel with purple, blue, green opal glistening up at you. He knows his work and is helpful and informative, and has lots of eye candy.

 

Bonnie made the rounds of the whole building, and then settled in with the first things we saw when we entered the tent! She proceeded to spend a long time choosing well-matched gemstone earring sets. Now she has plenty of work to do, but is excited to have such nice items to work with! I talked with a lot of vendors while she was there.

 

lancodiamond

I discovered Lasco Diamond Products. They had a great selection of rotary tool bits. I purchased a couple of new slicer bits that just came out. I will definitely put these to use with my Dremel and Foredom when I get back to my shop. If you need a rotary tool bit, they will have what you need, and I found them to be very friendly and knowledgeable.

wingatemug

My best find of the day was a coffee cup featuring Wingate Pass Agate. I was promised these would be available at the Tucson Gem Shows while at a street fair earlier in December.

We went back to the Kino show again, for some afternoon shopping adventures, with our daughter. Inside the tent, and outside in the vendor areas, we took another look at the normal quirky things there, including a reduced pile of buffalo heads from the last time we were there.

A large tent way in the back had vendors selling slabs of rare rocks. One vendor had slabs of Larimar. He had more Larimar than other vendors I have seen, and of good quality. He advised us that rough Larimar chunks are no longer coming out of the Dominican Republic, but only slabs are being shipped out. I picked out a special piece, and will likely go back to study his pieces further.

I bought a piece of Dinosaur Bone of an unknown color. I plan to cut it tomorrow and will show you the colors after I cut it. I love the gamble.

ammonitesinfossil;plate

Ammonite Fossil Plate

A fine fossil plate containing ammonites, probably from Alberta Canada, as many of the fossils had an opalized exterior. I thought this would be a wonderful item to put bright lights on and trip over in your home.

squid

Squid Tree

I saw a tree trunk carved into a giant squid, fish, and what not. I took a picture, since it is hard to explain.

 

 

Another quirky thing was a Steam-punked Water Buffalo skull, again hard to explain! We even saw a whole booth for sale for $1800. You could get right into business!

The weather returned to the mid 70s today, sunny, beautiful. It was a Saturday and very crowded and busy at Kino, so we decided to take off and return to shopping after the weekend is over. We like to shop, but not risk our lives doing it. We’ll take the day off tomorrow. We want to do a little work on some of those items we have acquired, so stay tuned!

Tucson Gem Shows-Beads and Bones

S0156043

Miles of Beads at IGM

55 Rainy, snow sprinkles in the air (No kidding)

S0176048

Three hours to just skim the surface here. The more we looked, the lighter our wallet.

Our day started earlier than usual at the International Gems & Minerals location at the Gem Mall. IGM is the largest bead dealer we’ve seen here in Tucson. Strictly a wholesale dealer, they open early, so they can sell to other vendors in town before they have to open at 10. It is really large, and not super well organized, so you might find something at one side, and they later find something similar that you like better several aisles over. And you have to ask for all prices (which is a pet peeve of Bonnie’s). But they had a large team and numerous people assisted us while we were there, and even though we are not a big buyer, they treated us very well.

In the Los Angeles area they have a shop and warehouse, with bead cutters and lapidarists that they employ worldwide. I chatted with Abdel Khattab, the owner of IGM, who has been in business for over 40 years. Bonnie shopped while I discussed products with him. It’s amazing the things you can learn by picking the brain of a someone that is a pioneer in the gem trade.

S0186049

Bonnie loves her new “Bead Lady” Cart

S0206058

You recall me speaking “lovingly” of Bead Ladies toting van-sized suitcases so they may deposit all their beads. Because we were such good customers today, IGM gave Bonnie a pull-behind two-wheel cart of her very own. Now she has a small cart like a Bead Lady wanna-be.

S0256079S0236072S0286085

After lunch we had time for a quick stop at the Grand Luxe. This has some rocks, but mostly ethnic products, dresses, antiques, dragon sculptures, etc. Dan Lopacki has bead relics as well as hand crafted cabochons. We have often talked Victoria Stone over the years, and he has a pretty selection of them.

This show was so busy that I observed one vendor asleep in his room, apparently equally as excited about this show as we were. With cool temperatures, Bonnie was the only shopper in the courtyard.

We left that excitement, and afterward stopped at the Mineral and Fossil Co-op. We read in the Arizona Daily Star about a rare Triceratops skeleton nicknamed Bob. One of the largest Triceratops skeletons ever assembled with original bones, this is 65% original bones, and was found on private property in North Dakota. It was found, and excavated from 2003-2014, when it went on display at the Barnes County Historical Society in North Dakota. A decline in oil revenue resulted in Bob being put up for sale. Everyone involved hopes Bob can continue to live in the US. It is for sale at GeoDecor inside the Mineral and Fossil Co-op. If you have a spare million plus, please buy him so he can continue his life in the Americas.

Even though this co-op is a wholesale venue, the public can still go in and look at the fossils, including Bob. Other highlights here were wooly mammoth and mastodon fossils, a baby mammoth, a wooly rhino. A wooly mammoth skeleton was rebuilt with added fur, resembling what he probably looked like, as well as a wooly Rhino and a baby Mammoth with fur.

 

The largest pair of Mammoth tusks ever found (around 250 pounds each) is here. They were found by gold miners north of Fairbanks, Alaska, and were carefully preserved over six years before being ready to be shown.

Down the hall is a gallery featuring petrified wood furniture and décor. Most impressive was a 20 feet x 4 feet table slab from the Arizona Petrified Forest. Wall hangings, bright colors, browns, cut table slabs, this place has some real eye candy.

S0306087

Almost eaten by a Megalodon

A Megaladon Mouth reproduction with real teeth hangs in one gallery. The real teeth are attached in their respective locations. These teeth were collected over many years with the intent to build an authentic representation. The largest tooth is over 7 inches. Measure that out and be in awe! We have seen this “guy” several times over the last few years. Each time I am reminded of how fortunate we are not to have these fellows filling our seas today. They had a voracious appetite!

If you can, you should stop into this interesting place, and if you can, be sure to buy “Bob”!

Fossil Books (Literally they are made of fossils)

We had a short stop at Kino, took a few pictures, and covered a little more of that show. The treasures of the day were several small Lodelite Cabs, as well as discovering a very fine small, Star Rutilated Quartz in a $30 pile. This one was worth at least five times that. I’ll get some pictures of these fine gemstones later. Bonnie found some very fine Turquoise Beads and I picked out a strand of Dino Beads for a future project.

After a break, we spent the rest of the day searching through the shows at the strip. Yes, we found many treasures at these Hotel Shows. I bought some Sphalerite/Galenite; this stuff is very cool. I just skimmed the surface of these Hotel Shows. For those never having attended these shows, all the hotel rooms and the courtyards are filled with rocks, gems, and fossils. I also found an Owyhee Agate Cab that looks exactly like Sleeping Bear Dunes.

The shows we attended were The Rapa River Show where our friend Jeff Anderson sells agates. He showed me a spectacular Purple Passion Agate. I bought some Blue Lace Druzy, and a couple of colorful agates from Patagonia (Not Condor). I hope you enjoy all the pictures from today.

A Combined Effort Produces a Fantastic Thomsonite Pendant

Sue, A longtime patron of our jewelry, brought me a Thomsonite brooch that had been in her collection for many years. She wondered if I could convert it to a pendant.
Snob Appeal Jewelrysuefront

This was, arguably, the finest North Shore Thomsonite I’d ever seen. I thought I could just cut off the clip, wrap it with a prong set, and be done with it. The more I looked at the vintage brooch, the more I thought it demanded a rework by a goldsmith rather than a wire wrap by me. Sure, I could have wrapped it; took her money and ran; but I felt the character of the historic piece deserved a stately simple solution.

Fate showed itself at our next Rock Club meeting, when I won the door prize; a custom made pendant by one of the club’s master silversmith’s Ken Schug. I told Ken that I probably did not need one of his pendants (we laughed together over my win), but told him I had a project for him. He agreed to a pin removal from the brooch. I no longer have the delicate tools needed for this removal. Although I am a trained Silversmith myself, I gave it up for wire wrapping and sold my Silversmith tools years ago.

Let me talk about what I found out about the brooch. First it was 18kt gold and custom made. Unbelievably meticulous effort was used by the master Goldsmith that produced it (probably in the 60’s), used small grey seed pearls, that were prong set and glued surrounding the oval Thomsonite cabochon. Because of the pearls, we could not use a torch for soldering the piece. A Laser for soldering was required, as lasers produce little or no heat.

Snob Appeal Jewelrysuerear

Rear view.

After Ken removed the pin and associated brackets from the brooch, I went to Korner Gem in Traverse City. Korner Gem is owned by my pal Kevin Gauthier. We refer customers to each other regularly. I traded the gold left over, for a new bail; soldered to the former Brooch Mike (one of the Goldsmiths’ at Korner Gem), soldered a bail on, using his laser. I payed for the time taken, and some laser time, but the price was much less than if I had not had a this trade of gold.

I took the pendant with me the next time I went to the Upper Peninsula, and Sue came and picked it up when I was doing jewelry demonstrations at Copper World in Calumet. She was very pleased.

The pendant turned out fantastic, and you could not tell that this was a conversion. I enjoy the camaraderie of jewelry making networks, rock club buddies, and appreciate skillful work from others. My customer was delighted, and even though I was only the director of this work, I too was very pleased. Because of good fortune, and having skillful friends, I was able to provide Sue with something new from her something old.

Petoskey Stone Hunting-Can It Get Any Better?

Bonnie hunting on the gravel pile they removed from where I hunted down below.

Bonnie hunting on the gravel pile they removed from where I hunted down below.

Under normal circumstances I would look out my window and see snow falling on the already snow-covered ground, and wind chills below zero. So what is the deal this year? December 27th; no snow on the ground and a foggy soupy look outside. It is 45 degrees. Let’s see; 45 degrees and fog means wet ground. Wet ground means the Petoskey Stones will turn from invisible to visible. Can it get any better? YES IT CAN!

Bonnie and I packed up the Broll, buckets, and Treasure Scoops threw them in the truck and off we went to one of the private gravel pits we hunt. We are not allowed to hunt when the pit is being worked, but they don’t work the pit in the winter. Can it get any better? YES IT CAN!

Dream hunting for the Petoskey hunters.

Dream hunting for the Petoskey hunters.

Even a blind squirrel could see this nut!

Even a blind squirrel could see this nut! I can get a pink one and another one in one scoop!

We know just before winter a pile of gravel was stockpiled for spring, and we know the pit will be wet where the gravel was removed down to near the water line. Petoskey Stone Hunting should be great. I have my waterproof insulated Gortex boots and Carhardt rain gear, just in case it rains. Can it get any better? YES IT CAN! It started raining!

Bonnie forgot her rain gear, but had a fairly waterproof winter coat over two sweatshirts. Yes this IS normal for this woman. I really don’t see much of her as we hunt different areas of the gravel pit. I know that we have many blog followers that have never hunted Petoskey Stones, so I decided to document this trip. Waterproof camera in hand so you can follow along.

I hunted down in a pit where a large amount of gravel was removed to create a giant pile of gravel. Bonnie, the more agile of us enjoys scurrying around on piles, while I enjoy wading, disregarding the cold water seeping through my boots. My goal today is to pick enough to fill a 4 gallon bucket. Bonnie’s goal is to search areas she knows I won’t go. Can it get any better? YES IT CAN!

A perfect white Petoskey Stone.

I started hitting the mother lode immediately. Man those Petoskey’s stand out in the water. All sizes, shapes, and hues were being exhumed. I saw something very unusual. A perfect Petoskey Stone, pure white in color. It was so white, I could almost see a glowing aura surrounding it. I’ve got to get a picture. I think it would be cool to make a piece of jewelry and be able to track the pendant back to its origin. A special Petoskey for the bucket. Can it get any better? YES IT CAN!

Here's a pink one.

Here's a pink one.

I’m finding two, three, five, and more Petoskeys’ within a foot of each other. I can scoop up two or three at a time. Can it get any better? YES IT CAN!

Can I find a big Pink Petoskey Stone? Yes I can; several in fact. Not all big, but very nice. I’m finding Favosites, Horn Coral, Crinoid Stems, and all forms of Devonian Soup. Can it get any better? YES IT CAN!

A nice big Petoskey.

Can I find a fist-sized Petoskey? Yes, almost immediately after the question forms. I love big, solid, Petoskey Stones. I’m hearing, off in the distance, the soothing sound of stones as they sort of thump and drum as they are thrown into a plastic pail. I know the Petoskey Queen is harvesting a good crop also, up above me. Can it get any better? YES IT CAN!

Why do you need extra weight in the Broll you might ask?  Can I take this Garden Rock?  Answer:  If you want to haul it.

Why do you need extra weight in the Broll you might ask? Can I take this Garden Rock? Answer: If you want to haul it. What a gem of a woman...

I’m tiring fast. Bonnie is skirting the edges of the puddled area, while I continue to wade. Soon my Broll bucket is filled and Bonnie has half a bucket also. She already took a bunch to the truck, so we are golden. I am wasted, beat up, and my leg is killing me, but it’s amazing what you can overcome when greed sets in. Bonnie took the Broll up the road to meet me at the gate. I took all the other rocks, buckets and scoops and headed out, picking as I went back to the truck. Can it get any better? NOPE! what a day.

Angels all over the House

Is the Quincy Mine Haunted?

Halloween 2014

I saw something in this picture I'd not previously noticed.

I saw something in this picture I'd not previously noticed.

I was looking through some old photos Bonnie took of the historic Quincy Mine #2 Hoist Building in Hancock, Michigan today. I saw something I have never seen in the picture. Something ghostly and very frightening. (Twilight zone music playing).

Close-up  WOE! I'm not going to be able to sleep tonight.

Close-up WOE! I'm not going to be able to sleep tonight.

The mine was opened in 1846 and continued operation until the early 1967. Deaths were not uncommon in all the copper mines. No one knows exactly how many miners died while mining Native Copper as records were not carefully compiled, but I assume many spirits still lurk about around these old mines. The picture certainly proves that, don’t you think?

Custom Projects of a Recent Sort

Beautiful Turquoise from Battle Mountain, Nevada

Beautiful Turquoise from Battle Mountain, Nevada

I am hesitant sometimes to try new Gemstone material, but I bought a piece of Turquoise from Battle Mountain, Nevada, at one of the Arizona shows. After cutting this stuff, I found it is absolutely wonderful. I have never cut natural Turquoise so hard. It was almost Quartz-hard. You can see why I like it. it sold the first time I put it out.

Custom jewelry pieces have been a backbone of our business for as long as we have existed. I love when someone contacts me in person or via the web, with an idea for a piece of jewelry, or simply brings a rock to one of our art shows to make something for them. Unlike most people that wire wrap, I cut most of my cabochons from rough rock. I know most wire wrappers don’t cut because of the crowds around cabochon dealers at the major trade shows; all wearing wire jewelry that they made from these cabochon. Even I, on occasion, find a cabochon I cannot pass up. Pre-holidays is a busy time around here, whether it be cutting rocks people find, or making custom pieces from rocks/gemstones that patrons provide.

A quality Petoskey Stone was removed from this ugly wire pendant.

Over the years, after seeing what kind of work I do, people will bring in jewelry that some other artist has created. Generally these are what I refer to as “amateur jobs”, and they generally are from the “Lee” family. Most of you know the Lees’; Home-Lee and Ug-Lee. One time a lady had a gorgeous Victoria Stone Ug-Lee wrapped in tarnished Sterling. Sometimes I am brutally honest, and in this case I told the lady that her pretty Victoria Stone deserved better. It wasn’t long before she came back to my booth and told me to fix the Lee wrapping. I did a rush job, and she was delighted when she returned the next day. I even wrote a blog on this, if you care to take a look.

http://www.snobappealjewelry.com/blog/2011/07/victoria-stone… y-to-beautiful/

After removing the Petoskey cabochon, I re-wrapped the stone as it deserved.

After removing the Petoskey cabochon, I re-wrapped the stone as it deserved.

yellowsajJanet brought in a very fine Petoskey Stone in a Lee wrap. If you know anything about Petoskey Stones, they are almost pure Calcite, and Calcite is a softer stone. This particular stone was grooved around the edge with a single piece of 16 or 18 gauge Sterling surrounding the stone in the aforementioned groove. It was twisted wire, making it even more distracting from this lovely, clear, stone. This technique of “grooving” is a simple way to created a fast, cheap, wrap, and in general is used for harder Silica stones.

By grooving a Petoskey Stone, it makes a weak edge, and two things can happen. 1. When you tighten the wire, the edge can (and often does) flake or break. 2. Because of the soft stone, the wire cannot be tightened enough to secure the stone in its’ grip tightly enough. Glue can be used, but then you see glue around the edge. In this case Janet’s pendant was literally falling out of its frame. Some related advise–I recommend no one buy a Petoskey Stone Ring. No matter what you are told by anyone selling you a Petoskey Stone Ring, they do scratch. I am constantly re-polishing them for people, but you can only do so much. Never buy any ring with soft material in it. Petoskey Stone Pendants are generally great, but still if you are wearing them, they can be scratched by zippers, metal buttons, or other harder objects. Pendants, unlike rings, can easily be re-polished.pinkbeadpendant1

Another customer brought in a couple large rectangular beads with holes drilled through them at the top with a mediocre finish. I cut across the beads just below the hole, re-shaped the cabochons so they were thinner, and less harsh. By rounding the edges and re-shaping these, I was able to produce a more pleasing shape to wrap. After reshaping them, I polished them and was pleased at how much better they looked. You can see the finished results.

I am also including a couple other recent projects for your viewing pleasure. Did I mention the 22 9mm Greenstones I made for one discriminating lady?

Nancy always brings me interesting projects.  This is an example of a Laker she brought me for cutting and wrapping.  It turned out so wonderful.

Pima Mine Tour

Giant Pima Mine with mill complex in background

Giant Pima Mine with mill complex in background

Eighteen miles south of Tucson near the town of Sahuarita is the giant Pima copper mine. Currently the mine is 2.5 miles long by 1.5 miles wide and approximately 1200 feet deep. Each bench within the mine is 40 feet high. In 2012 the mine produced 134.3 million pounds of copper, in concentrate.

The Pima Mine is part of the Mission Complex of mines.

The Pima Mine is part of the Mission Complex of mines.

Unlike the mines in the Copper Country of Michigan where large solid masses of native copper where the norm, the copper in the Pima mine is microscopic and is extracted from the ore by crushing the rock four times in ball mills which resemble large rock tumblers and the copper ore is crushed by steel balls within the tumblers for copper extraction, until it is a dust-like concentrate. When the metal is extracted the remaining crushed rock is hauled away to huge waste piles and the copper concentrate is sent by truck to a mill in El Paso where copper plates are formed. Also in this concentrate is small amounts of gold, silver and molybdenum. Enough of these minerals are extracted to pay the almost $2 million electric bill each month!

Giant dump trucks look small in the distance.

Giant dump trucks look small in the distance.

Giant dump trucks that are so big they need to be brought in in parts and assembled onsite work up and down the ledges within the pit. After being loaded with copper ore by a gigantic electric crane the copper ore is transported to the onsite Ball Mill building. When the pit is so massive and deep when you look at the trucks from the top, they appear to be very small, but standing next to them, you would see that one tire is around 12 feet tall.

We saw a large area within the mine where drills were working to make holes for explosives. Each day between noon and three explosives are set off in the mine. Their job is to lift the ground up and then settle right back down, loosening the ground so that the giant shovels can do their work. The reserve life of the Mission Mine which includes the Pima Mine is 2033.

No harsh chemicals are used at this mine. This fact is stressed by the tour guide. Some mild acid is used, but the extraction of copper concentrate takes place in giant open vats where the copper floats to the top and is skimmed off and dried to form the copper concentrate. How does copper float in water? The answer is old technology used in washing miner’s clothes! A wash lady discovered that by adding pine oil to the soap the tiny bubbles would float to the top with attached dirt from the miner’s dirty clothes. The mine uses this same technology using pine oil to float copper to the top, skim it, and the oil is recirculated to combine and rise again.

ASARCO (American Smelting and Refining Company) Grupo Mexico obviously the company started out as an American owned company but was bought out by Grupo Mexico. They have been producing copper for over 100 years. Beside the Mission Mine complex the company also owns the Silver Bell and the Ray Open Pit Mines in Arizona.

From a rockhound standpoint other interesting copper related minerals are occasionally found in the Pima and other mines of Arizona. Those include malachite, azurite, cuprite, chalcopyrite, some other arsenides, and rare earth minerals. It seems unusual to me that the Arizona mines have slightly different associated minerals than Michigan mines. Datolite, Chlorastrolite, Mohawkite, and Prehnite are distinctive to Michigan mines.

If you get a chance and are in the Tucson area, this is an interesting and inexpensive tour to take.
