STONE OF<br />

THE MONTH - FOSSILS<br />

The stone of the month for <strong>November</strong><br />

is Fossils. The word Fossil<br />

can evoke many images since<br />

there are so many and are found<br />

everywhere in nature. Fossils can<br />

mean specimens, petrified woods,<br />

dino poop, shells. The possibilities<br />

are endless.<br />

Please bring in your specimens or<br />

jewelry pieces that fall under this<br />

category. Be sure they are clearly<br />

marked and labeled as yours.<br />

Also check out the great story on<br />

page 8 that was submitted by Don<br />

Cronauer on Fossils and the one<br />

on page 7 by Karen Dave’ which<br />

focuses on Fossils in Jewelry.<br />

Thanks to Don & Karen for making<br />

my last issue a good one! Mary<br />

OCTOBER PROGRAM<br />

The History and Collection of<br />

the Lizzadro Museum<br />

of <strong>Lapidary</strong> Art<br />

The program for <strong>November</strong> will be<br />

a presentation on the history and<br />

collection of the Lizzadro Museum<br />

of <strong>Lapidary</strong> Art.<br />

Dorothy Asher, Graduate Gemologist<br />

and Director of the Lizzadro<br />

Museum of <strong>Lapidary</strong> Art has lectured<br />

around the country on the<br />

Museum's collection. She will present<br />

the history of select pieces in<br />

the Museum's permanent collection<br />

and also provide insight into<br />

Joseph Lizzadro's life and his connection<br />

to the <strong>West</strong> <strong>Suburban</strong><br />

<strong>Lapidary</strong> <strong>Club</strong><br />

President’s Message - by Joanne Samuel<br />

Hi everyone!<br />

Hope everyone is doing great.<br />

<strong>November</strong> has arrived, and now<br />

we are going to start seeing<br />

Christmas things being put up.<br />

Wow! Where did the year go?<br />

To start, I would first like to<br />

thank Terry Licko for a wonderful<br />

presentation. She does<br />

some great work doesn’t she! I<br />

would also like to thank the October<br />

team for the great snacks,<br />

they really out did themselves.<br />

I would also like to send out a<br />

special thanks to all the participants<br />

in moving the items from<br />

the shed. It was a big job but<br />

we got it done.<br />

But now to more important<br />

matters, we are coming to the<br />

end of our 50 th Anniversary<br />

year. It would be great to do<br />

something nice at the annual<br />

meeting. We are currently taking<br />

donations of items cut or created<br />

by club members for door<br />

prize drawings during the Holiday<br />

Luncheon meeting in December.<br />

Please give your items<br />

to Jose.<br />

Also remember that <strong>Lapidary</strong><br />

Day at the Lizzadro Museum is<br />

on <strong>November</strong> 21 st .<br />

As a reminder, if you have photos,<br />

newspaper articles, or even<br />

miscellaneous items (CGMA flyers,<br />

or Curry’s Action flyers) it<br />

would be great if you could get<br />

me copies or even e-mail them to<br />

me. It would appreciated. I<br />

have started the club’s scrap-<br />

book with what<br />

I have so far,<br />

but more material<br />

would be<br />

nice. I am sure<br />

everyone is going<br />

to love how<br />

it turns out.<br />

Another great<br />

way to commemorate<br />

our<br />

50 th Anniversary year.<br />

For the month of <strong>November</strong> the<br />

stone/ activity of the month are<br />

“Fossils”. Since the club is less<br />

focused on Fossils, it is nice to<br />

highlight something different.<br />

Fossils are great because they<br />

are similar to books as they can<br />

tell stories of the past. Some<br />

stones can also be fossils for example,<br />

turtella. So if you have<br />

any interesting fossils bring<br />

them to the meeting.<br />

It cannot be overstressed that<br />

while the <strong>Club</strong> Board members<br />

provide much of the planning<br />

and organization of these events<br />

for your enjoyment, none of it<br />

would be possible without the<br />

participation of the club members<br />

as a whole group. If you<br />

have any special skills, knowledge,<br />

resources or even just some<br />

spare time to volunteer, please<br />

contact a board member and let<br />

us know.<br />

If you plan on attending the<br />

Holiday Luncheon, please let<br />

your intentions be known to<br />

club Treasurer, Jose Ponce.<br />

Happy Creating! – Joanne

board that this will be her final year as editor, after<br />

several years of service. Fortunately, Pat Koko<br />

transition.<br />

Webmaster report: Don Shore encourages others to<br />

submit club photos for inclusion on the website.<br />

Previous Business meeting: The recent presentation<br />

by the President on the financial history and<br />

will be presented in the Opal<br />

Next general meeting: Program: Terry Licko has<br />

graciously offered to present her recently created<br />

observation. Carl is refining<br />

his techniques, and<br />

the displays show a wide<br />

variety of color, pattern,<br />

and shapes. Thanks for

Program: Long time WSLC member, Terry Licko,<br />

presented a professionally produced DVD depicting<br />

her abilities as an award winning artist. The<br />

program highlighted the source of inspiration, and<br />

challenges in the actual creation of the piece. It<br />

was an amazing history of samples of her work<br />

over the years. Thanks for sharing samples, the<br />

stories of how the piece was created and the beautiful<br />

photography. Some of the items were also on<br />

display, so members could see and appreciate the<br />

actual item.<br />

Special offer: Thanks to Don Cronauer who offered<br />

his two tickets to a special exhibit at the<br />

Field Museum. It was a thoughtful gift to a member<br />

few days.<br />

motion by Jose Ponce and second by Lee Herrera.<br />

OCTOBER PROGRAM<br />

REVIEW - by Barb Freeman<br />

Long time WSLC member Terry Licko<br />

provided the October Program entitled,<br />

Jewelry Design and Inspiration. This professionally<br />

produced DVD provided a pictorial survey of some<br />

of Terry’s jewelry created over a span of approximately<br />

35 years. Terry relates that she created the<br />

jewelry as a creative outlet, for its beauty, technical<br />

challenge, and to compete in regional and national<br />

events. Competition in the past was a grand event<br />

with numerous submissions.<br />

The quality of the DVD was excellent, with meaningful<br />

content and professional photographs. Several<br />

of her items were on display so members could<br />

view the actual pieces included in the DVD program.<br />

The narrative not only sounded good, but<br />

also stressed the creative aspects, techniques, and<br />

technical challenges. These are high quality items<br />

that are visually outstanding.<br />

The following review encapsulates several components<br />

of her body of work. This will be a brief re-<br />

view to bring back to mind the wonderful depictions<br />

of the jewelry. Several pieces won awards, including<br />

one’s at national levels. Another item was published<br />

and highlighted in the <strong>Lapidary</strong> Journal.<br />

Many techniques were depicted including casting,<br />

chasing, repousse’, gold plating, free form wax in hot<br />

water, etching in acid, pierced wirework, reverse patterns,<br />

pegging of gems and intricate linkages. Layering<br />

created visual depth but required extensive planning<br />

and how to fit the sections together. A variety<br />

of stones were included such as black jade, black<br />

mother of pearl, coral, blue lace agate, and various<br />

colored stones.<br />

There is also great variety in inspiration including<br />

the dusty miller plant, items associated with the sea<br />

and oceans, and birds such as the peacock. Even the<br />

holiday or seasons became a feature such as hearts<br />

and snowflakes. Art Deco style was also incorporated<br />

in a few pieces.<br />

Terry’s work includes simplicity and complexity.<br />

Each item in itself is a work of art. This description<br />

merely highlights and gives a small idea of the<br />

breadth of Terry’s collection. Recognition and thanks<br />

to Terry Licko for sharing her extraordinary history<br />

with our group.<br />

2010 Dues & WSLC Holiday Meeting<br />

FOSSILS IN JEWELRY - by Karen Dave’<br />

Fossils and jewelry, what’s up with that? Well, you’ve got to admit, there’s something kind of neat about<br />

having a gazillion year old animal or plant piece with you. Like wearing shark teeth or a meteorite – it's<br />

just kind of cool.<br />

So, what qualifies as a fossil? Are they rare? Is it unethical to use them in jewelry? Are they difficult to cut<br />

and set?<br />

Fossils are the preserved remains, or trace, of a prehistoric plants or animals. Prehistoric is older than<br />

10,000 years 1 – not so old in the grand scheme of things. The most commonly known are dinosaur bone<br />

and petrified wood. Dinosaur footprints are also fossils.<br />

Most fossils used in jewelry are petrified; the original organism has been replaced by minerals. The exceptions<br />

are old amber 2 and defrosted mammoth ivory.<br />

Just as with gemstones, some fossils are rare and some are not. Some are plentiful and of good quality and<br />

many are not. In the U.S., fossils collected on private property belong to the land owner and can be legally<br />

traded. Caution must be used when on government land, however.<br />

High quality specimens are not generally used in jewelry as their value is higher uncut. A complete identifiable<br />

dinosaur bone is worth more intact than its jewelry sized pieces would be. Mammoth and fossil walrus<br />

ivory are being used in place of elephant ivory. Petrified wood and fossil sea creatures are not particularly<br />

rare.<br />

Most petrified fossils can be worked with the same methods that we know and love, and would use for a<br />

non-fossil stone. Hey, it is a stone!<br />

FOSSILS - by Don Cronauer<br />

A fossil can be defined as a remnant or trace of an organism of<br />

a past geological age. These fossils may include: bones, skeletons,<br />

leaves, stems, and imprints such as trails (including footprints)<br />

and bark impressions. Many other articles have been replaced by minerals and they are considered<br />

“fossilized.” In summary fossils are almost classified as anything “old.” Some of these things may be colorful<br />

and pretty, while some are dull. Some even are used in making good jewelry.<br />

Considering that the universe is believed to be more than 13 billion years old, and the solar system and the<br />

earth older than 4 billion years, there ought to be a lot of fossils. The real challenge is to find them, identify<br />

them, and try to understand how things have changed over time. Yes, I do enjoy using fossils to make<br />

unusual jewelry.<br />

Chicagoland is fortunate to be located near the Mazon Creek site of the Illinois<br />

Basin outcrop of Pennsylvanian sediment. Mazon Creek is located in<br />

the vicinity of Coal City and Braidwood, IL. You may remember the location<br />

of the picnics that we held at the Abrell’s summer home. The area was<br />

mined in the period of about 1870 through 1930. During the mining, a<br />

great number of concretions were brought to the surface and fell into spoil<br />

piles, creek beds and the like. These concretions or nodules are composed of<br />

siderite (iron carbonate) that formed around animal and plant parts. During<br />

the decay of these parts, they hardened up due to release of carbon<br />

dioxide that reacted with iron-containing silt. Generally speaking, these<br />

Pecopteris -ref 5 Neuropteris -ref<br />

specimens were formed about 300,000,000 years ago. They are representative of animals and plants that<br />

lived near or in the water at that time.<br />

This area was part of an in‐land sea located near the equator. The surface of the area changed somewhat,<br />

and it moved quite a bit north due to plate tectonics and the shifting of the earth. To an extent, it’s just<br />

luck that these fossils formed here and they are available for us to examine.<br />

There are other sites throughout the world with ages between 700 million years<br />

and even 20 thousand years Their characteristics are often very different than<br />

those from Mazon Creek.<br />

The first aspect is that Mazon Creek fossils can be found within about 50 miles<br />

of Chicago. I found it was best to join a club like ESCONI (Earth Science <strong>Club</strong><br />

of Northern Illinois) to get to the right places. My first search was at a mine tailings<br />

pile. It happens all the time – specifically, I found a beautiful shrimp fossil!<br />

Shrimp I’ve been trying to find something better since, but nothing has come close! The<br />

most common finds have been jellyfish (sometimes considered “blobs”), clams,<br />

parts of shrimp and other animals, and a few worms and sea cucumbers. I have found few plant remains in<br />

part due to the locations that were chosen. Additional specimens have been obtained through purchases<br />

and trading. Selected pictures are attached to present representative Mazon Creek fossils.<br />

Of all of the fossils found at this site, the most interesting is the “Tully Monster”<br />

that is found only in Illinois. The Tully Monster (Tullimonstrum gregarium) was a<br />

soft bodied animal that was probably an active, swimming carnivore. It was<br />

round or oval in cross section and tube-like with a tail that had horizontal fins and<br />

a dorsal fin, all of which were triangular. It also had a long neck with a "jaw" that<br />

contained eight small, sharp teeth. There is no evidence that the throat went<br />

down the neck. It seems more likely that the neck or proboscis was a muscular organ<br />

used to pass food to the mouth. Of particular interest, there was transverse<br />

bar that passed through the body. This bar had “eyes” on the ends. My Tully<br />

Monster specimen is about 1 inch in diameter by about 7 inches in length when<br />

the neck is considering. The following are recommended references:<br />

Get better Tony!<br />

it dawned on me exactly how “unprepared” I was<br />

to make such a stop. My daughter was wearing<br />

shorts and flip flops, and I didn’t have my medical<br />

kit! So I was definitely prepared to hunt, but not<br />

my daughter, and definitely NOT to deal with the<br />

consequences of something bad happening.<br />

In the future I am going to give a good bit more<br />

forethought to my impromptu stops especially if I<br />

have my kids in tow and I would strongly encourage<br />

you all to do the same. If she had been bitten<br />

by that little snake it could have been very bad!<br />

Be safe on your trips and travels, and always consider<br />

how you can better prepare for events you<br />

may encounter in the field!<br />

Always Prepared! Are you<br />

Sure? A Safety Note<br />

by Owen Martin, AFMS Safety Chair<br />

I like to think that I am always prepared to make a<br />

quick stop at any out crop of opportunity that I encounter<br />

in my travels around the country. Rock<br />

hammer, bucket, loupe, I usually have all those<br />

things with me.<br />

So it was this last month when we were picking up<br />

my daughter from a summer camp in central Texas.<br />

While waiting to check in at the hotel I spied a beautiful<br />

looking road cut about a half mile from the hotel.<br />

I wouldn’t be able to look at it that night, but on the<br />

way back home I was sure I could convince my wife<br />

to stop for a few minutes.<br />

The following morning that is exactly what we did.<br />

My daughter even thought it looked good so she decided<br />

to join me while the rest of the crew stayed in<br />

the minivan and listened to the Jonas Brothers or<br />

Miley Cyrus. I got pretty excited since within about a<br />

minute on the outcrop I found my first loriola echinoid.<br />

It was a really cute little one and better than<br />

what I was hoping for. My daughter came over to see<br />

it and we promptly found 3 more in the next couple<br />

of minutes. Things were going really well!<br />

Or so they seemed, but then a few minutes later I<br />

heard my daughter scream and she was only about 10<br />

feet away from me so it gave me quite a shock! I was<br />

immediately on top of the situation (or so I thought)<br />

and discovered that she had just had her first encounter<br />

with a baby diamond back rattler. Luckily<br />

they scared each other and the snake quickly headed<br />

under a rock.<br />

So as I picked her up and hauled her back to the van<br />

Thank you Everyone!<br />

Hard to believe this is my last issue<br />

of The Opal as Editor. Seems<br />

like I just took it over recently,<br />

but also seems it has been a large<br />

part of my life forever. It actually<br />

has been 5 years! A lot has happened to me in<br />

those 5 years. Some good and some not so memorable.<br />

But I still come out swinging, so I guess that ‘s<br />

good.<br />

Thanks to all of you who have contributed various<br />

articles, book review, meeting minutes, board meeting<br />

minutes, President messages and the like. I<br />

hope you extend the same graciousness to the new<br />

Editor, Pat Koko. I leave you in good hands.<br />

I’m outta here - thank you Mary Prosek<br />

MORE THANKS FROM<br />

LYLE & LUCY BACKUS<br />

We want to express our gratitude to our friends at<br />

the <strong>West</strong> <strong>Suburban</strong> <strong>Lapidary</strong> <strong>Club</strong> and School for<br />

the wonderful retirement dinner they treated us to<br />

on October 16th. For he last 10 years, Lyle and I<br />

have enjoyed meeting so many students and hope<br />

they received the knowledge and the desire to continue<br />

cutting stones. Also, we shall never forget<br />

your kindness given to us through the years. In<br />

all, we appreciate your generosity inviting us to a<br />

wonderful dinner. The food and company were<br />

excellent and we could not have asked for a better<br />

evening as the weather cooperated to make for a<br />

perfect night. Thank you friends!<br />
