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.

Edible Geodes!
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?

Jewelry Making Tip
A WOW! 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.

Andalusite is a rockforming mineral

Andalusite forms during the regional metamorphism of shale. It is found

In these rocks, andalusite is often associated

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,

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/

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.
