ROCKHOUNDING (COURTESY OF WIKIPEDIA)
The first amateur geologists were prospectors looking for valuable minerals and gemstones for commercial purposes. Eventually, however, more and more people have been drawn to amateur geology for recreational purposes, mainly for the beauty that rocks and minerals provide.
One reason for the rise in popularity of amateur geology is that a collection can begin by simply picking
up a rock. There are also many clubs and groups that search for specimens and compare them in groups as
a hobby. Information on where to find such groups can be found at libraries, bookstores, and "gem and
mineral shows". Tourist information centers and small-town chambers of commerce can also supply valuable local information. The Internet can also be a useful search tool as it can help find other amateur geologists.
The amateur geologist's principal piece of equipment is the geologist's hammer. This is a small tool with a
pick-like point on one end, and a flat hammer on the other. The hammer end is for breaking rocks, and the
pick end is mainly used for prying and digging into crevices. The pick end of most rock hammers can dull
quickly if struck onto bare rock. Rock collectors may also bring a sledgehammer to break hard rocks.
Good places for a collector to look are quarries, road cuts, rocky hills and mountains, and streams.

THE GOLDEN NUGGET
GET TO KNOW YOUR 2013 BOARD MEMBER JAMES P. ANDERSON
I am a retired Alabama state worker. I guess I have done a lot of things in my life and one of them is
to have developed an interest in gems, minerals and such. That includes my being a member of the
Dothan Gem and Mineral Society. I have not been very active in that interest lately, especially in the
last few years. But my wife, Betty, suggested that we take a look at the club here and some interest
has been rekindled and so we joined the club and in 2013, I was invited to become a board member.
Outside of family, I guess my strongest current interest is in the sport of Hang Gliding. Be careful
about asking me any questions about that sport. I will happily bore you forever on that subject.
June's birthstones are the Alexandrite, the Moonstone,
and the pearl.
The meaning is health and longevity.
Its birth flowers are the honeysuckle and the rose
MONTGOMERY GEM & MINERAL SOCIETY MINUTES MAY 9, 2013
Our Annual
Gem Mineral
and Jewelry Show
will be at a new
location in
December:
Alcazar Temple
The meeting was called to order by President Thad Cheatham and guests Crystie
Willard and Theresa Frank introduced themselves. Since there was no April meeting
due to inclement weather, the minutes for the March session were approved. Iris
McGehee read the Treasurer's report and it was approved by a show of hands. Lynn
Stauch indicated he had been asked by the Crump Center staff that we do a better job
of cleanup after our meetings. David Sherrod was approved to handle shop purchases
for the club and will buy a new trim saw blade and see which wheels need replacing
on the Genies. The gem and mineral show at Tannehill state park will be held June 1,
2 and is an excellent place to procure quality rough for cabochons. Thank you notes
from Faires Austin and Keith Harmon were noted. Iris McGehee stated that the deposit has been made to Alcazar Temple for our upcoming show in December. There
will be no May field trip. Refreshments were served and rock bingo was enjoyed by
the 40 rockhounds who were present after which the meeting was adjourned.
THANK YOU FROM JEANETTE RITCH
I would like to thank David Sherrod for meeting me at the shop on
Saturday, May 25. I won one of the scholarships to William Holland and
I decided to take the cabochon class. Since I wanted to get familiar
with the shop and machines, David was a big help. He sliced a quartz
rock from our property, drew a template on it, cut it out and then "cabbed"
it. (attached are some pictures) I can't wait to get to William Holland and
try my hand at it. THANK YOU, DAVID!
I would also like to mention that my nephew, Kent Aasand has graduated
with a degree in anthropology from Mississippi State. Here is a link to an
article on the MSU website about a project he has been working on
http://msstate.edu/web/media/detail.php?id=5993. I thought it was
interesting, you never know what you will find when you go on a dig!

hot dogs & buns and other goodies which will be furnished by the club. RESERVATIONS
REQUIRED BY June 11th.
Eliminating Flats - (by Ted Robles)
A while back, someone was saying that he was having problems with getting "flats" on his cabs, that
there was insufficient “give” in his wheels, and it didn't seem to make any difference no matter how much
pressure he applied. That was his first mistake.
Diamond and corundum ate two different animals; relatively speaking, about the same difference as
between quartz and chalk. If you "lean into" a diamond wheel, you will get lousy results (flats, etc.) on
your stone, and your wheels will wear out long before their time. On diamond, you try to do your cutting
(and everything else) by almost not touching the wheel. Use essentially no force. Don't "grind" the stone,
let the diamond wear it away, but keep it spinning. The technique is simply to use the whole face of the
wheel, and keep your cab moving. Any time you stop, you just bought a "flat". Can't help it! It's the same
principle as sharpening a knife on any emery wheel. If you don't want notches in your blade, you keep it
moving. Do almost all of your cutting on the coarsest wheel you have. If you leave any flats on the preform, you're going to have them on the final piece. Can't help it.
And finally, practice, practice, practice. Machines, like people, take some acquaintanceship before you
really know what you can get out of them.

FIRE AGATE
(CONTRIBUTED BY JACK KIRKLAND)
Fire agate, a variety of chalcedony with an ancient and fiery beginning, is an all natural gemstone found only
in certain areas of Arizona, northern Mexico, and other parts of the southwestern United States. Approximately 24-36 million years ago these areas were subjected to massive volcanic activity during the Tertiary
Period. The fire agates were formed during this period of vulcanism when hot water, saturated with silica and
iron oxide, repeatedly filled cracks and bubbles in the surrounding rock, often forming a botryoidal (grapelike) growth.
Fire agate gemstones have beautiful iridescent rainbow colors, similar to opal, with a measurement of hardness on the MOHS scale of between 6.5-7 which prevent the issues of cracking and scratching. The vibrant
rainbow colors found within fire agates, created by the Schiller effect as found in mother-of-pearl and fire
opal, is caused by the alternating silica and iron oxide layers which diffract and allow light to pass which
forms the interference of colors known as fire. Besides the thin limonite and/or geothite iron oxide layers
there is no actual objects inside the gems, the fire agate visual effects arise from light interference within the
microstructure crystal layering of the gemstone.
Fire Agate Gemsare one of the hardest gemstones to produce, taking highly skilled lapidary skills and the
creative talents of a true artist. Dedication, patience and time will be needed if you plan on producing
quality fire agate cabochons, but the final rewards are truly spectacular. The fire agate stone also has a large
metaphysical following with the fire agate meaning and properites of being an excellent protection stone
which reflects negative energies, and healing properties for the stomach, nervous and endocrine systems.

THE GOLDEN NUGGET
COLLECTING SELENITE (CONTRIBUTED BY JACK KIRKLAND)
Read more at http://www.fws.gov/southwest/refuges/oklahoma/saltplains/
Selenite is a crystallized form of gypsum. Chemically, it is a hydrous calcium sulfate. Gypsum is a common
mineral that takes on a great variety of crystal forms and shapes. On the Salt Plains, the crystals are formed
just below the salt encrusted surface. They are seldom found deeper than 2 feet below the surface.
Crystals take on the characteristics of their environment; the finer the soil, the more clear the crystals. Iron
oxide in the soil gives the crystals their chocolate brown color. Because these crystals form in wet soil, sand
and clay particles are included within the crystal. These particles often form an "hourglass" shape, found only
in this area. Other foreign objects in the soil, such as sticks, rocks, bones, and even cockleburs, are sometimes
included as the crystal forms.
Single crystals, penetration twins, and clusters are the typical crystal shapes most frequently encountered on
the refuge. Exceptional individual crystals measuring up to 7 inches long have been found, along with complex
combinations weighing as much as 38 pounds.
In certain places on the Salt Plains, gypsum and saline solutions in the soil are sufficiently concentrated to
promote crystal growth. When temperature and brine conditions are ideal, the crystals may form very rapidly.
When heavy rains or floods bring great quantities of freshwater to the plains, some of the selenite crystals may
go back into solution until conditions are right for recrystallization.
As long as nothing happens to change the mineral content of the waters draining into the Salt Plains, these
crystals will continue to form, just as they do today.
Crystal digging is permitted April 1 through October 15, sunrise to sunset.
No special permit is required. Collectors are permitted to remove up to 10 pounds of crystals plus one large
cluster for their personal use in any one day.
How is it Done?
1. Use a shovel to dig a hole about 2 feet deep and 2 feet across until you reach wet sand. You may feel the
shovel break through the crystals as it goes down. This cannot be helped as there is no way of predicting
exactly where a bed of crystals is located.
2. Allow 2 or 3 inches of water to seep in from the bottom.
3. Use your hand or a container to splash water gently against the sides of the hole. The agitated water will
wash the soil away from the crystals.
4. When you find a crystal formation, continue splashing to wash it free of the supporting sand and clay.
5. At this stage of the process, the newly exposed crystals are wet and fragile. Use great care in removing
them.
6. After removing crystals from sand, place them where sun and wind will dry them. Egg cartons or other
containers may be used for transporting the crystals.
