From attending, volunteering for, and being members of gem and mineral clubs in New York, Texas, Pennsylvania, and attending camps, seminars and intra-club retreats with people from all over the United States, we consider ourselves gem, mineral, and fossil club aficionados. So whether you are considering joining a gem and mineral show for the first time that perhaps you found on an events page, or you are a veteran of gem and mineral clubs, this primer on clubs will prove to be a valuable resource on what to expect from a gem and mineral club and how to have more fun.
First, consider what you are seeking from a club. Is it the academics and education of gemology, geology, paleontology, or archaeology? Are you seeking rockhound partners and buddies? Are you seeking to use a work-shop for cabochon or lapidary arts? Are you seeking fellowship with a group that meets outside of their monthly meetings? These are questions to ask as you search for the club that is right for you.
The answer may be to join more than one club…
Each club does have a different style, and you can tell what that is from their homepage, or if they do not maintain a homepage, then ask someone from the club. Some clubs have access to facilities offering a complete workshop; saws to cut giant geodes in half, cabochon machines, polishing wheels, lapidary tools, faceting machines, and kilns to heat your wire-wrapping or jewelry projects are for member use! Some clubs maintain all that equipment in their own private clubhouse! Is a workshop something you seek to pursue and hone your hobby? If so, then find the club that offers that equipment.
Now the clubs like this may not always have a special monthly speaker, but the clubs who meet in a rental space, hotel banquet hall or college facility do very likely provide different speakers each month. The clubs in big cities, where a workshop or clubhouse would be impractical, or impossible to acquire and maintain rely on other facilities for monthly meetings and shows, so to keep membership growing, those kinds of clubs keep a lively roster of speakers on their calendars.
Is your goal to get out and rockhound? Do you seek to explore old abandoned mines? A question to ask a club is do they throw and organize field trips? You can often times find out the answer on their homepage. There is often a “field trip” section, much like this Rockhound page. If you can’t tell, then ask the club. Sometime being in a big city can make field trips a challenge. Most people in New York City or Chicago do not have cars for instance. A field trip would require permission and arrangement to visit a site, a bus or fleet of vans, and if it rains, the field trip is canceled. So big city clubs may not offer rockhounding field trips. The age range of the club can also set the tone for interest in rockhounding and field trips. For a club whose members’ days of getting out into the field are past, you may not find these opportunities.
So what is the best approach to becoming involved with gem, mineral, and fossil clubs? The answer is to join more than one. The dues are annual and range from $15 per year to about $50 per year on the very high side. You may live in New York but find the newsletter from a club in Texas is chock full of so many good tips about polishing gems and minerals, cleaning rocks from the field, and other anecdotes that you belong despite the geographical distance.
So join more than one club, to have access to a workshop when you need it, field trips in the spring and fall, the chance to hear academic and scholarly discussions in geology and paleontology, and make new friends during the whole gem and mineral club experience!
Now the source and formation of Herkimer Diamonds is of particular interest to us here at American Geode because the Herkimer Diamond was formed in “pockets” not unlike the pockets that formed geodes. Most quartz crystals grow, over the course of millions of years attached to a matrix, attached to the surrounding rock or stone. So in those formations only one end of the quartz crystal grows to its point. With Herkimer Diamonds forming inside pockets, freed from the surrounding matrix stone, they grow points on both ends.
The Herkimer Diamond began forming nearly 500 million years ago in pockets within a sedimentary rock called Dolostone (Dolomite and Limestone). Sedimentary rock, different from its two cousins Igneous rock and Metamorphic rock, is formed by layers of mineral and organic matter under hundreds of million years of pressure. As more layers of mineral and organic matter are deposited, this increases the pressure and weight on the lower and earlier layers of sedimentary rock below. The Dolostone covered Herkimer County during the Cambrian Age, when Herkimer County was also the bottom of the sea that spanned across North America.
Now this is the part of the Herkimer Diamond formation that is similar to the way geodes are formed: organic material, plants and sea life would die and be buried under new layers of sedimentary stone. When these plants and other sea life would decompose under the rock, they release gases, and this gas is what formed the “pocket.” Evidence of this organic, plant material succumbing to decomposition is clear when you see the black shiny flakes of Anthraxolite that surround or leak from these pockets. Anthraxolite is a carbon compound and by-product formed when organic material breaks down.
So as the organic material decayed and broke down it became a gas, trapped below layers of sedimentary stone. Air creates its own pressure inside a substance, so the air pressure was carving out its own cavity from the inside out. These air pockets became the pockets we rockhounds discover as we crumble, break, and peel away layers of the dolostone. Over the course of 200-250 million years the layers of sedimentary rock increased and grew, and this increased the pressure and heat on the buried dolostone. Also inside each of these air pockets were various quartz and carbon elements and other compounds “feeling the heat” from being buried below layers of sedimentary rock.
Under this pressure of the sedimentary layers of rock, and the ensuing heat, the quartz and other compounds inside these pockets began to transform themselves. Finally, over the course of 300 million years, the glaciers that sat atop Herkimer County began to melt, and washed away layers of the sedimentary rock, and allowed the compounds and elements inside these pockets to cool down and then crystallize.
An important question to answer right now is “why are the Herkimer Diamonds double-terminated?” The answer is that quartz does not adhere to the dolostone, therefore the quartz trapped inside these air pockets did not attach to the surrounding matrix host stone. The process left the quartz crystals free to fully crystallize unattached and allowed both of the ends to grow into fully terminated points. Many Herkimer Diamonds are found as clusters attached to one another. They adhered to one another during their crystal growth formation, but again did not adhere to the dolostone interior of the air pocket. The value of Herkimer Diamonds is determined by size and their opacity or translucence. The larger and more translucent Herkimer Diamonds are worth more to a collector or jeweler than the smaller opaque specimens. Knowing the history and background of the Herkimer Diamond however lends a premium in our opinion when you are considering adding Herkimer Diamonds to your collection. They are not commercially mined due to various New York state laws limiting mining in the state, and most of Herkimer County is being used today by happy grazing cows, sugary apple orchards, tart cherry trees, farms of squash, cabbages and onions, and wine grapes. We have recently gained access to heretofore unmined and barren acres in the Herkimer County area on the same geologic slope and ledge as the traditional Herkimer Diamond mines. We are in consultation right now with the owner about constructing a pole-barn over this new Herkimer mine so we can mine year-round.
