GUIDE TO COLLECTING AGATES; WHERE AND HOW TO FIND THEM
There is a wide variety of
agates, and many collectors include them in their collections. They are
attractive, common, and hardy. Because of this, not only are they great for
jewelry, but also for a wide range of other specimens.
Are you ready to find out
more about these incredible gems?
Continue reading because
we're going to go deeply into this topic. Here, you'll learn about agates,
where to look for them, and some creative ways to use them once you've
unearthed them.
What exactly are Agates?
Chalcedony, another name
for the silica dioxide (SiO2) material from which agates are fashioned, makes
up the bulk of an agate's composition. Glass, quartz crystals, and opals are
all fashioned from the same element.
Minerals' crystalline
structures are often the source of their distinguishing properties. Its
cryptocrystalline structure gives chalcedony its name. The meaning of the word
"crypto" indicates the underlying framework. Even with a microscope,
these crystals are very small.
In the spectrum of cryptocrystalline
SiO2, which also contains flint and chert, chalcedony may be found.
Transparency is what sets chalcedony apart.
Agate has historically
referred to banded chalcedony. In modern usage, it refers to stones that
feature primarily transparent chalcedony inclusions.
These may be anything from
simple banded stones to exquisite Turkish agate. Collectors of agates have an
unfathomable selection of stones from which to choose.
On the Mohs scale, agates
sit at a fairly respectable 7. Because of their malleability, they have
traditionally been used in jewelry and decorative arts. The stone's resilience
makes it ideal for novices. Furthermore, they are slow to produce results.
Remember that agates,
along with many other types of transparent chalcedony, are what you really need
to take away from this article.
Exactly how Many Distinct Agate Varieties Exist?
There is an overwhelming
variety of agates to choose from for the avid collector. Some of the most
beautiful agates are only recognized by their location, making a complete list
almost impossible.
However, there are certain
broad classifications that may be made for agate:
Banded
agates- They are often devoid of significant inclusions. They
are instead built up of gradated layers of material. The best banded agates
feature strong contrast and crisp lines, which may be a subtle but important
distinction.
Moss
agate- Inclusions in moss agates mimic moss or other tiny
plants, thus the name. Though they come in a rainbow of colors, green is by far
the most common. As a rule, they are very see-through, giving the impression of
great depth.
Plum
agate- In comparison to moss agate, the inclusion structure
in plume agate tends to be more substantial. Some agates may be difficult to
classify since they have characteristics with both plum agate and orange agate,
although generally speaking, plume agate is the oranger of the two.
Dendritic
agate- It’s named for its tree-like inclusions, is often seen
with a black background and a milky color. In certain regions, they are more
frequent than other forms of agate and may be easily identified. This opal
should not be confused with the common opal, which also has dendritic
structure.
Iris
Agate - a transparent piece that flashes a spectrum of
colors in the appropriate light. While high-quality collector specimens are in
great demand, they are seldom utilized in jewelry because of the precision
required to achieve optimal optical effects.
Fire
agate- It is a kind of agate with minute specks of
iridescent iron particles. In most cases, they are housed in transparent
chalcedony and sliced in a way that reveals their bubble-like 3D structure.
Eye
Agate- The banded, spherical inclusions that characterize Eye
Agate are a distinctive feature of this gemstone. Depending on where the stone
was mined, these inclusions may be solid colors or form intricate, attractive
patterns.
Tube
agate- When cut and polished, the tiny mineral tubes that run
through agate's background become visible.
What has been provided
here is by no means an exhaustive list. Agates, like jaspers, go by whatever
name the person who discovers it chooses. That which has been provided so far
are some broad principles to follow.
The location of an agate
is often used as its name rather than the stone's actual characteristics.
Exquisite specimens are the well-known Lake Superior Agate and the Hampton
Butte Plume Agate.
While most agate nodules
are uniform in "style" throughout the stone, even two slabs cut from
the same nodule can have strikingly different appearances. Agates have depth
despite their apparent transparency due to the abundance of their inclusions.
Amazing agates are like seeing through a portal to another dimension.
Where Can I Get Some Dyed Agates?
Many inexperienced rock
hounds have been duped into purchasing fake, colored agates. In the hands of
unscrupulous vendors, they may pass for natural, particularly if the buyer has
no idea any different.
Dyed agates are easily
distinguished because they include gradations of the same dyed color. The most obvious
clue is a very saturated color that has a very dark tone. While agates may have
some beautiful colors, the exact shade of each area of the stone will nearly
always be different.
Nothing prevents you from
purchasing an attractive specimen or display item. Keep in mind that any
sizable piece of agate with a uniform color was probably dyed. If it were
genuine, you'd have to pay an extremely high price for it because of its
scarcity.
Where Do I Go to Find Agates?
Despite their exotic
appearance, agates may be found in almost any part of the planet. Agates are
more likely to be discovered in areas where volcanic activity has occurred.
Nodule agates are the most
highly prized kind of agate. Typically, the size of one of them is between 12"
and 3". Streams and riverbeds are rich in nodules. One of the simplest
ways to spot them is by using water, as they will stand out from the background
of regular stones.
Agates may be found very
much anywhere in the United States, although not all of them are of the same
quality.
This root beer agate is a
typical example of a boring agate. Large nodules resting on the limestone at
Jalama Beach on California's Central Coast are prime examples. There is an
abundance of it, and it's not hard to discover larger-than-average examples.
That's the rub, right? The
fact that it consists mostly of shades of brown means that most collectors
won't go wild about it. After slicing a few specimens and discovering that they
were... well, dull on the inside, I quickly lost interest in it.
It's still agate, but most
collectors are looking for the real deal.
The following are some of
the top locations for agate:
·
Oregon
·
Washington
·
Idaho
·
Arizona
·
New Mexico
·
Minnesota
Agates of exceptional
quality are most often found in concentrated regions, which may or may not be
on public property. It is incumbent to the rockhound to ascertain whether or
not they are legally permitted to scavenge for rocks.
The hunters themselves keep
many prime locations a secret.
The reality is, agates may
be found in an almost infinite number of locations. Despite the fact that I
have already mentioned beachcombing for Root Beer Jasper in California, I admit
that it is not at the top of the list.
Nipomo Agate, on the other
hand, may be found in the clay of a nearby town. It's an orange agate with
thick marcasite plumes that give it a metallic sheen. For a brief while, it
even became a fashionable gem.
You are thus not
necessarily out of luck if you do not reside in one of the aforementioned
states. Great agates may be found just about everywhere, however you may have
to go far to get the rarer kinds.
How to find Agates in the field without stress?
The greatest bet for a
novice rock collector is a nodule. Vein agate and other varieties of agate
exist, but they can only be discovered by mining. Nodules are the Holy Grail of
collecting for the vast majority of enthusiasts.
Consistent
practice is needed here.
Finding agates in the wild
will need some time and effort. When a rock collector is familiar with the
region, they may be able to see a nodule from quite a distance. To be a
competent hunter, you need a set of innate abilities that just cannot be
taught.
Although, there are lots
of things to be done in order to achieve much
Dried-Up Riverbeds and streams
Agate nodules are often
discovered in tiny streams or dry riverbeds. Agates are much more readily
identified in the presence of running water; a clean, wet agate will reveal its
true character.
Streams
The greatest place to
search for tiny stones piled up in streams is on the bank. Because of their
extreme density, agates often "sit" in crevices and curves. It's
worth your time to go through these relatively modest heaps.
Most nodules will have a strikingly
different color from the local rock norm. Agate's unique cryptocrystalline
structure also gives it a distinct feel. A common trait is a "waxy"
surface sensation. They could be substantially heavier than the local stones,
although this isn't the case in areas with a high concentration of volcanic
rocks.
Dry
River Beds
A rock pick is an
essential item to have on hand in arid regions. Check out any areas where
stones are stacked to see if you can deduce whether or not this was ever a
riverbed. Most of the time, the finest times are depressions. It may be
necessary to do some digging to find the smallest agate nodules, since they
tend to sink to the bottom of a pile of larger stones.
Moving the rocks in one
direction until I reach a layer where the stones are 2" to 4' in diameter
is my preferred method of working. If there is a lot of dust, a water bottle
will show that any stone is not an agate.
Matrix is present on
certain agates and is usually the host rock. These may be eliminated in the
future.
Physical Attributes
In most cases, nodules
have a round or egg form. Surfaces are often pitted where matrix has been worn
away. They will typically have a form that is distinctive from the local
stones. Focus on dissimilarities and you'll soon discover more.
In addition to smaller
agate pieces, you could uncover fragments of bigger agate nodules. These could
have been ground down into smaller flakes, or they could still be one large
conchoidal flake. All that matters is how long ago the stone cracked.
There may be instances
when you encounter something you need more clarification on. The nodule may
still be buried totally in the host rock, for instance. That's why it's crucial
to acquire shape recognition skills.
Use one of the agate's
attributes if you don't feel like carrying back a lot of stones that could or
might not be useful. Conchoidal fractures are evident, meaning that a nodule
may be easily cracked with a sharp blow.
If you don't have a rock
pick, you may use a hammerstone instead; just give the stone a solid whack and
you'll see right through it. When first broken, an agate will always reveal a
smooth, waxy or glassy interior.
Don't fracture specimens
in the field if you can help it if you're going to be cutting them. Even though
you find out that you are wrong, it's not the end of the world. Frankly, agate
is going to be harsher on blades than anything else you’ll discover.
You'd be astonished at how
many you can locate with a little time and practice.
ROCKHOUNDS ESSENTIAL TIPS FOR HUNTING AGATES
Many rock hounds like
going on agate hunts along the shores of Lake Superior or the beaches of the
Pacific Northwest. Correctly so!
Agates are the crown jewel
of any rockhound's collection because of the incredible diversity of colors
available and the ease with which many of them can be picked off the seashore
in superb gemstone condition.
However, even for the most
seasoned rock hunter, agates may be surprisingly evasive. So if you want to go
agate hunting and see if you can fill a pocket with the earth's own tumbling
jewels, you may want to read the advice I've compiled below.
Key
Tips for Successful Agate Hunting
Useful Advice for Finding
Agates
1. Locate Beaches That Have Exposed Gravel Beds
The beaches of Oregon are
my go-to spot for agate hunting. Keep an eye out for exposed gravel beds
wherever your preferred agate hunting spot may be.
The vast majority of the
time, sand completely burys many of these gravel beds. Although agates are
rare, they may be found in plenty when the ocean decides to clear away the
sand.
2. Take Advantage of the Season of Winter
I like going on agate
hunts in the winter for a few different reasons.
First, during the colder,
wetter winter months, you'll frequently find yourself utterly alone if you live
in an area where folks like to gather. More agates for you, then!
For another, the winter
months saw the passage of some of the most severe storms. Sand and gravel are
carried by the strong winds and rains. During severe storms, agates that are
usually submerged in water or buried in sand are washed up on the coast and
made visible.
3. Put Your Back Towards The Sun
It's best to go agate
hunting when the sun is behind you. A good alternative to having the sun at
your back is to have it right in front of you. Given their translucence, agates
can appear to be flooded with sunlight at the right time of day, making them
much easier to find.
Further, the early morning
or late afternoon/evening hours can be ideal for agate hunting because the sun
isn't as high in the sky. This lower light angle makes the agates
"glow" and shine out from the surrounding rocks, making them much
simpler to detect.
4. Employ a Sand Sifter or scoop
We are avid rock hounds
and agate hunters who spend many hours scouring streams, beaches, and
shorelines for agates and other treasures. How often do we reach down to
examine a lovely pebble or a possibly hidden object? Innumerable times!
Therefore, I've taken to
utilizing a sand shovel whenever I go to the beach. The Sand Dipper is the one
that I personally use and advocate for.
The Sand Dipper is a
stainless steel ‘basket’ beach sand scoop that’s mounted to the end of a telescopic
aluminum rod. Simply stretch the pole to the necessary length, scoop up the
agate, and dump the excess sand and other detritus through the wire mesh
basket. The agate, seashell, or whatever treasure you were seeking is all that
remains. Also, you didn't have to go on your knees to obtain it.
5. Exercise Patience
There is a popular saying
that states that good things always do come to those that wait patiently for
it.
In the context of
agate-hunting, this remark has never been more accurate. From personal
experience, I can tell you that you could be in the heart of the world's most
prime agate-hunting ground and still go months or years without success.
Expecting to find a
pocketful of agates after spending only 15 minutes searching your rock collecting
area is unrealistic.
Your search for agates is
likely to take at least an hour. It's possible you'll come across some earlier,
but you shouldn't count on it.
You should plan on
spending some amount of time searching before any start jumping out at you.
6. Don’t be too sluggish while walking
Hunting agates can at
times become overwhelming.
One thing you should
ensure you do as you move along the beach or shoreline is to carefully look at
every single thing that you find on the ground especially the ones that catches our eye.
You can then stop, pick up
the item and observe and investigate properly. Then we keep going, looking
around at everything we can.
As a result of visual
stimulus overload, our brains begin to "shut down," making it easy to
miss agates that are in plain sight.
You may overcome this by
walking more quickly and training your brain to focus on the agates while
ignoring the other "beautiful stones."
7. Assurance in recognizing what you are searching for
A couple who spent 20
years agate hunting together is the subject of an article on miningjournal.com.
The husband had discovered several agates on their excursions, but the wife had
never even come close to doing so.
The husband, fearing that
his wife might give up, hid some agates on the shore so that she would discover
them.
Those agates were never
located by the wife, which is really peculiar. After walking by them many
times, she eventually located all of the agates that the husband had hidden. At
this point in time she has become an expert when it comes to spotting spotting
agates ever since.
The fact that she began
finding agates with increasing regularity attests to her growing competence in
doing so once she had the knowledge necessary to do so.
8. Finally, if all else fails, dig!
Spending time digging is
another effective method for finding agates.
If you have sufficient
energy to do this, by digging down through the different layers of rock piles
can yield interesting and nice results if done in the right spot.
When I am really running
late to the beach and the crowds have already had a chance to scour the hunting
grounds, that is when I resort to walking along the shoreline in search of
agates.
9. Keep out of the Crowds
I have already stressed
the significance of this, but I will say it again. You will have much more luck
in your rock collecting endeavors if you can avoid the throngs of people who
will inevitably be there. There are certain ways to increase your chances of
becoming the first person to discover the agates and so reduce the number of
others searching for them.
Your best bet is to be
there before the other agate hunters have even finished their morning coffee
and newspaper. There is no other activity where the adage "the early bird
gets the worm" rings so true as in agate hunting.
Secondly, you should look
for less popular beaches to visit. Canoe trips to remote beaches, where we
found many beautiful agates, have been some of my most fruitful agate-hunting
excursions. Most of the time, you can find agates, jasper, petrified wood, and
other interesting rocks on these beaches.
10. Don't forget to bring an agate!
This is an agate hunting
tip I found on Reddit.com and thought was great, so I made sure to include it
here.
Bring an agate from home
to use as a reference point if this is your first time agate hunting or if
you're exploring a new location. Drop it on a gravel bar once you get there to
see how it blends in with the other rocks and debris.
This will help you develop
the eye-hand coordination necessary to distinguish the agate from the other
gravel. After training your eye to recognize agates, you'll be able to find
them in stones of any color or form.
Agates:
what are they, exactly?
Agates are the banded, translucent
rocks commonly found in sand and gravel. The microcrystalline quartz that forms
agates takes many forms. In cases when their quality and color make them
suitable for use as a semiprecious stone, this is their most common use.
In the crevices of igneous
rocks, agates occur when silica in the groundwater is deposited. This explains
why you may find bigger agates with perfectly round faces. The volcanic rock
the agate developed inside served as a kind of a mold for the finished product.
Fortunately, Oregon is ideal for the formation of stunning agates.
In
what ways can beachcombers determine the origin of agates?
The variety of colors
present in agates is one of the things that fascinate me most about them. You
can find any color you can think of, and even some that are extremely uncommon.
The amazing spectrum of colors found in agates is the result of a complex
interaction between the many minerals that make up the stone.
If you find an agate on
the seashore, the first thing you should do is check its opacity (translucent
quality). When held up to the sun, all agates appear translucent, though some
are more see-through than others. The opacity of an agate is indicative of its
mineral content and crystalline structure, and as such, it is useful not only
for identification but also for determining the type of agate you have
discovered.
