Cuyuna Rock, Gem and Mineral Society The Agate Explorer June 2016 Building Committee Anyone who has been in the basement of the building where meetings are held is well aware that it is an old building in fair condition. The rent is very economical and we are lucky to have such a spot designated for just our Club. That being said, the Club has just signed a two year lease, but the long term future of the building is questionable. How long will it be available before we are asked to leave, due to a change in ownership, or that large and expensive repairs are needed that will outweigh the justification of keeping the building? Therefore the Board has determined that a building committee be formed to explore all options for an alternative club location for when the needs arises. If you are interested in being on this committee please contact any board member. Their names, phone numbers, and email addresses are listed on the back page.

Rarest Gems Youth Poster Contest #10 Jeremejevite Sponsor: The Summit Lapidary Club of Ohio Theme: “Amazing Agates” - a poster illustrating any type of agate, what it looks like, and where it can be found. Eligibility: children in 1st through 8th grade Contest Rules: Pronounced ye-REM-ay-ev-ite, this is a colorless, sky blue, or pale yellow stone, the highest quality of which comes from Namibia.

As of early 2015 Jeremejevite was selling for $2000 per carat. 2016 Show Below are a couple of photos from the show. The total attendance for the show was approximately 2900.

I have become aware of the fact that crystals and geodes are not just something that rockhounds like, but are a popular trend in the general population as well. So, I decided to do a little research and discovered that you can buy geodes at Target (online and at the store), and that crystals and geodes are an up and coming wedding decoration and for guest favors. And, then I found a really fun site where you can make geode pops (cake bites on a stick that look like geodes). The site is http://www.craftsy.com/blog/2016/04/geode-cake-pops/ So, who is going to make some of these and bring them to the picnic?

There were just under 3000 people in attendance at the show this year. The club table was very busy and so it was difficult to keep an eye on items that we are selling there. Requirements for members to qualify for the vending discount at the show are as follows: Next year we will use two display cases - one for the items being sold and one for the door prizes.

Diamond Discovered By Brad Smith www.BradSmithJewelry.com Steel shot in a vibratory or rotary tumbler works great to burnish and shine your finished silver pieces. But a common problem is how keep the shot clean. Carbon steel shot can get rusty if exposed to the air, and even stainless steel shot can sometimes develop a blackish coating that's hard to remove. My solution of choice to clean the shot is Classic Coke. Just pour an ounce or two over the shot and let the tumbler run for an hour or so. A bad case might require a second cleaning. Some folks like to let the bubbles in the Coke dissipate before using it so that gas pressure doesn't build up in the tumbler barrel. I've heard that it's the phosphoric acid in Coke that does the trick. While you're waiting for the shot to clean up, just settle back and enjoy the rest of the Coke. An astounding 404.2-carat diamond, the largest diamond ever discovered in Angola , was recently unearthed. This diamond, at almost 3 inches wide is the width of a credit card and virtually flawless. The Australian diamond mining company Lucama Diamond Company is the lucky owner of the now 27th largest diamond in the world! The large diamond is even more rare given its Type Ila rating, 2nd from the highest rating possible for diamonds. Type IIa diamonds make up only 1 to 2% of the world’s diamonds and contain very little to no nitrogen atoms. Pure diamonds are comprised of rigid carbon lattices, however, most diamonds have imperfections including nitrogen atoms. A typical Type IIa diamond will command a 5 to 15% premium and could be more in rarer large diamonds. Lucapa estimated that the 404-carat diamond could be worth upwards of $20 million. However, they note that pricing on diamonds this large doesn’t necessarily follow the same guidelines used for smaller diamonds. Lucapa now owns the honor of the largest Angola diamond, previously held by the Angolan Star at 217.4-carats. Lucapa has noted they plan to sell the diamond to fund further exploration and expansion at the Angola diamond mine. Lucapa Identifies Huge Kimberlitic Structure Lucapa continues to explore Angola for kimberlitic structures known to be associated with diamonds. They recently completed a gravity survey that identified a large kimberlitic structure that has “potential for a large diamond-bearing pipe (= high prize).” This kimberlite is located near one of their current mining blocks, which has produced large diamonds. Lucapa is not certain this new kimberlitic structure will contain diamonds but they are hopeful and continuing to define their resource. Mineral Encyclopedia— Andalusite Andalusite is a rockforming mineral that is mined for use in high-temperature refractories. Gemquality specimens are cut into faceted gems and cabochons. Andalusite forms during the regional metamorphism of shale. It is found in schist and gneiss at some present and ancient convergent plate boundaries where the rocks have been exposed to the temperatures and pressures needed for its formation. In these rocks, andalusite is often associated with kyanite andsillimanite. with cordierite in hornfels, granite, andgranitic pegmatite. Andalusite has a number of useful physical properties.

Zeolite – Zeolites are minerals that have a micro-porous structure. Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater. Zeolites also crystallized in post-depositional environments over periods ranging from thousands to millions of years in shallow marine basins. Naturally occurring zeolites are rarely pure and are contaminated to varying degrees by other minerals, metals, quartz or other zeolites. Yellowcake – The solid form of mixed uranium oxide, which is produced from uranium ore in the uranium recovery (milling) process. The material is a mixture of uranium oxides, which can vary in proportion and color from yellow to orange to dark green (blackish) depending on the temperature at which the material is dried (which affects the level of hydration and impurities), with higher drying temperatures prohttp://www.gatorgirlrocks.com/resources/ ducing a darker and less soluble materiglossary.html al.

Box 151 Crosby, MN 56441 FIRST CLASS MAIL The Agate Explorer June 2016 Official Publication of the Cuyuna Rock, Gem & Mineral Society Members of AFMS & MWF Notes from the President I would like to thank everyone that helped put together a great show, with just short of 3000 people attending. Saturday was a record breaking 2100!! I would like to start organizing the show for next year (May 6 & 7), when we are hosting the Midwest Federation meetings in conjunction with the show. We need to add a few more volunteer positions for next year after analyzing how this year’s show went. The first position is a “people coordinator” which Joanie Hanson has so graciously agreed to do. Dick and Meredith have agreed to take the first and last shift of the show at the door. Thanks! Sharon Smith will be show chair for another year. Thank you! We are really in need of a shift of tear down people from 4-8 p.m. on Sunday. The board has determined that for Club members to receive a reduced space price it will be necessary to volunteer at least 4 hours prior, during, or after the show. I was saddened by the number of Club members I saw who attended the show, but did not volunteer to help. There are jobs that anyone and everyone can do. We are hoping to do an agate pick after it rains. Watch your emails or (for those that do not have email) wait for a phone call for the next pick. The Iowa/Arkansas trip is pretty well organized, but there is still time to decide to join us. Other events in the future are the picnic, July 23rd, an estate rock sale, possibly in August, looking for cross rocks, and a trip to Michigan for copper hunting in late September.
