Lake Superior Agate Pendants and other Unusual Stones-On the Workbench

I’ve been cutting lots of recently acquired Lake Superior Agates since we arrived back from our winter in Arizona.

I suspect a couple fans will want this one.

A marvelous pastel Lake Superior Agate Pendant

I have to admit a recent Laker Pendant was put together right after cutting and polishing the stone. Sometimes a certain stone just make me eager to make something of it. The Laker I am speaking about has unusual banding and color; a tight reddish/brown fortification pattern in the top, and an entirely different pattern of wide white and peach banding on the bottom. The agate outdoes itself with this beautiful pink/peach. Pink Gold and Gold Gold wires enhance this nice stone.I named it Color-Wicking Lake Superior Agate Pendant.

Unusual Lakers like stirred Mocha

The second great Laker is an unusual dark carnelian with a pattern that looks like it was stirred in. The brown base agate bleeds though the white pattern creating a very rare yellow. The opposite side of the agate is eye-like.

Luna Agate found over 50 years ago.

Picture Petrified Wood.

As a bonus I show you a couple of cabochons of Picture Petrified wood from near Holbrook, Arizona. Also a few other cabochons that will soon be jewelry.

I have been very busy cutting stones and sorting through my treasures from the Tucson shows. I’ll share my favorites as I get more!

Variscite from Utah is a beautiful pastel.

Another blog is in the works for the near future on the 20 0r so new mini Greenstone Pendants I have recently made. Thanks to all our blog readers.

Tucson Gem, Mineral, and Fossil Shows-2014-A Silver Lining

Found in someones' discards.

We were not going to venture out today to the Tucson Rock and Gem Shows. There are shows closing down and the Main Event starts tomorrow. We plan on being in line when the main show opens in the morning.

I went out to The Rock Show and searched through my favorite random rock pile. The vendor that has the pile replenishes it daily. This is my third run at this rock-filled bin.

Silver Slabs in the tub. A surprise find.

Wire Silver-WOW! I wish I owned this.

These are now mine. I should be able to make great jewelry from these.

I saw some very fine Silver Ore the other day at this show. The ore came from the famous Bulldog Silver Mine in Creede, Colorado. The Mine is located on a ridge just west of Creede called Bulldog Mountain. A very interesting history is found at the Mining History Association. The mine was closed in 1985 due to depressed silver prices, but is in pre-development by Hecla Mining Company. There is lots of silver left in “them thar” hills. The name Hecla in familiar to everyone, like myself, that hunts in Michigan’s Keewenaw Peninsula. (We go there to collect Greenstone, Datolite, Prehnite, Mohawkite and many other jewelry-making minerals in that area, left after the copper miners left.) Calumet and Hecla mined Native Copper in The Upper Peninsula for many years, beginning in the 1880’s.

The Silver in Quartz from Creede resembles some of the silver that came out of Michigan’s Copper Country. I was shown a beautiful piece of Wire Silver from Creede that reminded me of the famous wire Silver from Kongberg, Norway. A great specimen indeed.

I was pleased to purchase these Native Silver slabs. I saw them the other day and they have been haunting me. Besides quartz and silver they also have barite, acanthite, and should make some wonderful jewelry.

Resting up for tomorrow…

Greenstone, Lake Superior Agates, and Custom Jewelry

I have been working on custom orders that mostly came from shows we did in the Upper Peninsula. These projects are always fun, as customers bring in Agates, Greenstones, and other U.P. rocks with ideas for jewelry.

The sister's Greenstones

After sitting in a drawer for 25 years, a pair of small Greenstones were rescued by Katherine and Judy. The Greenstones were already cut and polished, but needed a little extra work and TLC to bring them up to the standards they deserved. These lively sisters (and long-time customers) brought these stones to me and requested a wrap with “all gold and a fancy top”. A nice size for a Greenstone pendant, they converted into gorgeous jewelry . I love doing jewelry that has sentimental value, and these were not the only pieces of this nature I made this trip.

A custom piece for Nancy. Lake Superior Agate

Our buddy Nancy and her family have been long time lovers of our jewelry. She annually brings Lakers, and other interesting local gemstones, in for me to evaluate and make into pendants or polish. Nancy’s husband found what looked like a rather ordinary Lake Superior Agate (although large for a local stone), but when I cut the stone, it turned out to be a fantastic surprise. The reason the Lake Superior Agate is my favorite gemstone is the wide variations in pattern, colors, and types. The stone Nancy gave me was a mostly white, crack free, laker. I (and Nancy) were delighted with this stone. What makes this one special is the sentimental value that her husband actually found it. A great project. Thanks Nancy.

Shirley's Greenstone Geode. This one 1 3/4" across. I cannot believe someone would glue this in a spoon.

Our long-time friend Shirley has one of the most eclectic collections of my jewelry. She believes in supporting local artists, and loves U.P. rocks and minerals. I have fun sometimes in my shop when I see a certain stone, cut it, and immediately get a feeling that Shirley would like this stone. I make a pendant and when I get to a show where I know Shirley will appear immediately when the show opens, so I hide this special pendant (in plain sight) in my local pendant case. Shirley’s sharp eye and discrimination tastes, invariably spots this special pendant. The next time I see it, it’s around her neck.

This year she found a Greenstone Geode at another booth. The vendor had made a pendant with the stone glued into a spoon. I know, why would anyone do this? Shirley wanted me to free the Greenstone from the spoon and make a pendant from it. I had fun making a big, bold pendant. She likes Big, Bold, Pendants; she was very pleased with the finished results. This is a real one-of-a-kind..

Greenstone in matrix I found at a vendor booth.

The Greenstone pendant I made from that rock.This pendant is almost 3" tall. That's a biggun folks.

I found another Greenstone, entrapped in matrix, at the same vendor’ booths, and made a cash exchange with him. I put together a unisex pendant, and expect to wear it myself until someone makes me an offer I can’t refuse.

Before we went to the Keweenaw, I took a side trip to Canada to look at a rock collection. I bartered jewelry (plus some cash) for some of this large collection. One of the rocks was gorgeous;

A close-up view of a beautiful, odd, mystery rock. If you know what this is, let me know.

green and white in color, and even though it has been posted on the Lapidary Facebook site, no one has positively ID’s it. I made a pendant for John, the collection’s owner, and will make more jewelry in the future. My Facebook friends are hovering to get some of this stuff, but I think I will retain the 7 or 8 slabs I have until it is positively ID’d. It has the chatoyancy of Victoria Stone, and the color and starlike quality of chlorastrolite, but much bigger. Some of the material in this collection was obtained 75 years ago, so no telling what this is. It has been a fun research though.

Bonnie's Garden.

Amethyst in a salmon colored Laker. I called this one "Samethyst"

Our 36th Wedding Anniversary was last month. In honor of that and Bonnie’s love of gardening, I created a U.P. Thomsonite Pendant that I called “Bonnie’s Garden”. It is now in her private collection.

I have to show you a couple Laker’s I recently completed for our inventory. One is a red and white “Candy Striper” which is always a popular color combo, and one a rare Salmon colored Laker with Amethyst. Every amethyst Lake Superior Agate necklace I do sells as soon as I put it out!

It is not too early to start thinking of Christmas, especially if you have custom work for me. Now is the time to get your special stone to me; so I have time to do it justice.

Now is also the time to check out this website for special Christmas gifts.

There is so much happening right now with our business. We have grown every year, and expect 2014 will be no different. We try to treat our customers as friends, and if you order from us, like our website and/or like us on Facebook, you too can be kept up to date on all our adventures and jewelry. Let me know if I can do anything for you.

Keweenaw Rocks, Minerals, and Copper Country Jewelry

Our trip to Keweenaw was great.

Wire wrapping on the top of Brockway Mountain awaiting the sunset.

Even though we are older, less agile, and spry than we used to be, we had great adventures in the Keweenaw. I hit a mother lode of SISU Agate, and spent a few very hard days banging this agate out of hard rock. I cannot give you the exact location, but it is south of Copper Harbor. Bonnie says that EVERYTHING is south of Copper Harbor. This is fairly true, so this is a nice, vague clue.

The view from Brockway Mountain in just amazing.

The art shows in Eagle Harbor and Copper Harbor were very successful; as were our Demonstrations at the finest gift shop anywhere, Copper World in Calumet.

We consumed many Pasties and Vollwerth Hot Dogs, watched the Isle Royale Boat come into Copper Harbor while consuming a gourmet meal at the Harbor Haus. The waiters and waitresses do a can-can on the deck to welcome the boat each evening. In tune with the town theme, the restaurant has a huge double copper door, with warnings not to touch the Copper. It does get really hot it the sun, as you can imagine.

This is the Firebrick Pendant I made up on Brockway. It sold the next day.

We saw many old friends and met many new folks. I know we are getting a big following and a wonderful reputation, when we see women wearing our jewelry wherever we go up there. We were featured in the summer issue of the Copper-UP newspaper that featured Copper World with a color picture of our jewelry covering half the front page.

We found local miners willing to part with Greenstones, Datolite, and Thomsonite for some cash. I hand picked the best for future jewelry.

SISU (Cliff) Agate from my hole.

The only disappointment was we signed up (and paid money for) an organized hunt to the Central spoil pile that did not happen because the County had moved in a crusher and equipment. Another former fantastic greenstone and copper rock hounding location is disappearing to become asphalt, etc. Sad.

The weather was good and the bugs were sparse. Bonnie volunteers to go rock hunting and be bait for the remaining bugs, and they ALWAYS choose her. No further comments on that. She edits this, so I suspect a comment about this will be added. She is the jeweler’s wife, and is expected to suffer for being able to pick from thousands of pieces.

Random Pendants and Earrings of Lake Superior Agate, Datolite, and Firebrick.

I’m typing this as we navigate the Seney Stretch, M-28, a barren wasteland of scrub pine that is the longest straight stretch of Michigan road, flat also. You could go really fast out here except for Moose, Deer, Wolves, Bear and the like that you would be killed if you hit. The State has no bug-killing quota in the Seney Stretch. This is fortunate for all those that cross this area. An RV window can really take out a lot of bugs at once.

The roads are paved in copper in the Keweenaw.

When you look at the random pendant picture, take note of the far right pendant in the middle row.. It is a banded Laker floating in an Amethyst sea. I had four slices off this agate, wrapped them all, and sold four pendants in 5 days on this trip.

One day, while headed to the top of Brockway Mountain, I stopped to check out an outcrop on the side of the road. The roadway to the top of the mountain is in dire need of repair and is crumbling apart, but I noticed a glint in the blacktop. I was not surprised to see copper embedded in the blacktop. I have a friend that actually hunts copper on warm days with a metal detector in the roads. I will not say who this is for his protection from the law.

I have to say something about Firebrick for those that do not know what it is. When the Copper Smelters were build, they were made of brick. Over the years the Copper vapors and molten copper permeated into the brick and replaced everything except the Silica (Quartz) in the brick. When the smelters were torn down the copper bricks were disposed of by dumping them in the water, taking them to landfill, or burying them. Some were removed for landscaping or lapidary uses (bookends, jewelry, paperweights, etc.). I have a 70# piece I have been gradually cutting and making jewelry from it. This is a wonderful, rare, historic material and many purchase it not only for its’ beauty, but for its’ historical story.

We expect a return trip to the Keweenaw in October for colors and to dig more SISU. What a great time we had.

Mohawkite, Domeykite, and Algodonite

As I look at these names, I think what an unfriendly sounding bunch of names. I make natural stone jewelry out of this? How about calling it Silver Bullet or Shining Golden Bridal Stone? Instead this mineral has a name that reminds me of a donkey.

Gold Ore or Mohawkite? A real fooler.

Mohawkite was/is one of many local names for a copper ore comprised of Copper and Arsenide. The two primary Copper Arsenides in the Copper Country are Algodonite (Cu6As) and Domeykite (Cu3As). Between 1900 and 1901, 105 metric tons of Mohawkite were taken from the Mohawk Mine. Enormous masses of Algodonite also came out of the Ahmeek Mines. This area is on the north end of the Kearsarge Lode.

A silvery slab of Mohawkite. Siver coloration in probably due to high Nickel content.

I have sort of a love-hate relationship with any of these Arsenides. Allow me to explain my love-hate relationship with Mohawkite. Mohawkite is a local name for a mixture of Algodonite and Arsenian Copper found in the Mohawk and Ahmeek area Copper Mines. This material has been called many names in the past, and even today we hear solid pieces of Mohawkite called “Butchite”, another example of a local moniker.

Iridescent Mohawkite. The picture does not do this justice with it's metallic reds and Cobalt Blues.

While I love all the Keweenaw Mining District stones, like Greenstone, Datolite, and Prehnite, I dislike working with Mohawkite or any other Copper Arsenide. After cutting Mohawkite I seal the material using a lenghthy procedure I’ve developed over the years. After any Mohawkite cabochon is sealed it becomes perfectly safe in normal use.

What I do love about these Copper Arsenides is they are absolutely gorgeous. When this arsenide is intermixed with white Quartz, the effect is amazing. It makes beautiful jewelry, and has this ability to be, and look, like several other things. For example, it’s a real fooler when the golden Mohawkite couples with the white Quartz. You would swear it is Gold Ore from California. Customers love the jewelry I make from Mohawkite, and because it is found nowhere else on earth, it is another keepsake from the Copper Country that is totally unique. I suspect that the amount of Nickel, Cobalt, or other trace minerals in the Mohawkite causes some of this stone to remain stable in color, while others change to gold. The Arsenides are the cause of the iridescent phenomenon. I have found that in stones that contain a high level of Arsenides, the color change is almost instantaneous.

By sealing the stone, any potential toxicity is eliminated. The possibility of the stone tarnishing is prevented by my sealing process also. I think of Mohawkite as a Chamelion of sorts. When I get a cabochon shaped, I never know how it will react to oxygen. I cut some today that became iridescent within 5 minutes. I wanted a golden color so I went back and re-ground off the rainbow. The metal was silver in color when it came off the grinder. I put the cabs in water, and rushed them to my sealing area. I rapidly removed them from water, dried them. When I wiped them dry, they immediately changed to a golden color. I sealed them in time to inhibit them from changing to iredescent colors. I did leave several cabs to for a few minutes and sealed them when they rainbowed.

You see very few people making jewelry from Mohawkite, but I love the unusual look of it, and we sell many pieces of it. After my sealing process, the stone is perfectly docile and safe to wear.

My Mohawkite jewelry is popular at Copper World in Calumet, Michigan, I also sell this material on line. Mohawkite is challenging to find anymore, but occasionally I stumble over a good piece while exploring the piles. Remember that these Mohawkite mines are all on private property and should not be hunted without permission.

We specialize in jewelry made from rocks and minerals of Michigan, and Mohawkite is one I love to hate. You on the other hand will love it, especially when you get all those complements.

Working on U.P. Projects

Today let’s talk about some of the projects I brought back from the Upper Peninsula.

Sue's "super" Thomsonite

Sue has been a faithful customer over the years and she has brought me some amazing local stones for custom pieces in the past.

This time she brought one of the largest and most amazing Pink Thomsonites I’ve seen in a while. The cabochon was found in the Keweenaw 40 years ago, according to an I.D. tag that was on it. Thomsonites of this size and quality are very scary to work with because of the value and this one because of the size. Thomsonite sometimes just blows apart when you work with it on the grinder. Any harmonics created by the machine grinding wheels can send shockwaves into this material that sometimes just blows the stone apart.

I am always up to a challenge, but I also would hate to ruin a $500 stone. Thomsonite varies in hardness quite a bit, as well as crystal structure.

I had to re-work this stone to balance the shape and the dome. Believe me it was scary. This stone was very hard and solid (fortunately), and I was able to reform and re-cut it .

I was very happy with the way the wrap came out. As is my normal theory on wrapping I did not cover the beauty of the stone, yet I wanted the wrapping to be as elegant as the stone. I liked the way it came out; as did Sue.

Unusual blue coloration enhances this great little agate.

Nancy's ring.

Our friend Nancy brought several stones for me to assess. She enjoys the U.P. and rock hunting. Her daughter, Elizabeth, is also a rockhound. Several of Nancy’s stones had possibilities, and cutting when I got home produced an unusual small agate from the end of an otherwise plain stone. The stone had a strange bluish area. I have never seen this coloration in a Lake Superior Agate. It is hard to explain and lucky for you I took a picture. I made a ring for Nancy that reminds her of the U.P.

Elizabeth's wonderful pendant.

Elizabeth found a very cool ledge agate the next day and after cutting it and finding out how nice it was, I made a great little silver pendant for her. All these projects I really enjoyed. I love making my customers happy. Thanks to all of them.

You are not going to believe what is inside this stone.

The third project was my wife Bonnie’s anniversary pendant. You have seen the amazing copper-infused Datolite Pendant, but I don’t think you saw the ordinary looking rock it came from. You never know what might be inside the crust of a rock. I think that is why I love making jewelry. I’m the first person to actually see the inside of the rocks I cut for my jewelry.

The 35th Anniversary Pendant...SHE LIKED IT!

I would be happy to do some custom work for you. I can take your stones and create something wonderful just for you! What’s your dream jewelry? Let me make it for you.

Cliff Mine-Prehnite Hunting

The hounds are released on the Cliff Mine Pile.

The pile was bulldozed and the Copper Country Mineral Retreat hunt at the Cliff Mine began at 9am. A good crowd of eager hunters attacked the pile. A nice trench was excavated and some entered it while others, like me hunted the surface. The Cliff, even though hunted for over a hundred years by rockhounds, still produces some fine copper specimens as well as other copper associated minerals. Native American Indians hammered this copper in prehistoric times, and chisel chips left from their mining are found at the Cliff today.

A nice trench was excavated and our buddy Keith from Baltimore found his way into it.

A great view of the Cliff mine showing the trench that fellow rockhounds were searching.

Since I already have so much native copper, Bonnie and I spent the day hunting for gem Prehnite for our jewelry. The Prehnite at the Cliff formed in small veins maybe a few inches thick and is apple green and speckled with copper. We were quite successful and found good pieces with some help from Pam Hecht who is a good buddy and led the hunt.

Prehnite comes in various forms and colors in the Copper Country. One of my favorites is referred to as “U.P. Thomsonite” and is verigated, often with eyes. Prehnite comes in assorted pastel colors, the most common being pink and green.

A seam of Copper bearing Prehnite from the Cliff Mine.

Here is some of that Prehnite on my workbench. Notice the copper?

The Cliff mine was the first successful copper mine in the Copper Country of the state of Michigan. The mine is at the now-abandoned town of Clifton in Keweenaw County. Mining began in 1845, and the Cliff was the most productive copper mine in the United States from 1845 through 1854. Large-scale mining stopped in 1878. The Cliff was a fissure mine where the seams of copper were vertical.

Fissure mines are always interesting to search. I spent the day looking for gem quality Prehnite, and Bonnie and I found many nice pieces. These veins of Prehnite are commonly no more then an inch or so wide with a split down the middle as the Prehnite formed in from the outside of the vein and met in the middle. Much of this Prehnite is loaded with specks of Copper and is a pleasing apple green color.

Although amygdaloid and conglomerate deposits of the Keweenaw tended to be lower-grade than the fissure deposits, they were much larger, and could be mined much more efficiently, with the ore blasted out, hoisted to the surface, and sent to stamp mills located at a different site. Amygdaloid and conglomerate mining turned out to be much more productive and profitable than fissure mining, and the majority of highly successful mines were on amygdaloid or conglomerate lodes. The first mine to successfully mine a strataform ore body was the Quincy Mine in 1856. The most productive deposit, the Calumet conglomerate, was opened by the Calumet and Hecla mining company in 1865. (Mine information from Wikipedia)

I’ll be excited to cut this Prehnite and make some attractive pendants.

The NEW Seaman Mineral Museum.

The NEW Seaman Mineral Museum

The new Seaman Mineral Museum at Michigan Technological University opened not long ago with their first display from the Keweenaw set up.

Museum cases ready to be filled

The new building has slightly less floor space than their old location in the Engineering building. I think with careful planning they can get all the old material back in plus maybe a little more. The new building was designed to be added to and it really needs to be twice as big at least.

Some of the Keweenaw collection minerals

A generous donation from Thomas D. Shaffner and supporters of the Seaman and the University funded the building. Construction began auspiciously when an old mine shaft was struck under where the building was going to be replaced. This added costs to the building as that hole had to be filled. I thought that it would have been a great asset to just leave the hole open and charge for mine tours (OK, just kidding). Another option would have been to put the Fluorescent collection down there (you need dark don’t you?).

Lakers

Copper history display

Our good friend and famous artist, Susan Robinson, took Bonnie and I on a wonderful tour of the future museum. Susan’s husband Professor George Robinson has done a wonderful job coordinating the reestablishment of the museum exhibits. Susan is to be commended as chief specimen wrapper and unwrapper.

The gift shop is open and was busy. The biggest areas of the exhibits are still to be unwrapped and displayed, but they did get Keweenaw minerals out to make all of us drool over what we wish we might find this week.

Datolites
