What is the step 5 of geodes?
Step five: Down to the stream! Turns out, as we later learned, river rocks are not your best source for geodes but as we live in the foothills of the Catoctin mountains, law of averages says, everything is going to wash down hill eventually. Days of hand weighing stones. A very precise scientific process which requires holding a rock in each hand, balancing in the current, squinting one eye, and then screaming emphatically, “ I got one. I got one.This one is lighter.”
How are geodes formed?
A geode is formed by hydrothermal fluid deep underground depositing dissolved minerals into the inside a void or hole in rock , the voids are usually the result of a bubble of gas that was trapped in molten volcanic rock, the volcanic rock hardens with bubble shaped voids or holes where gas was trapped, and then much later hot hydrothermal fluid la
What is a geode?
Geodes are a roughly spherical rock with crystals inside growing inwards, often of quartz as amethyst and or cryptocrystalline varieties of quartz like agate or chalcedony, but there can also be various other minerals such as calcite and dolomite etc.
Which is lighter, a geode or a rock?
Step four: By carefully fitting the two remaining halves of the stone together, there was a smaller missing third chunk we never found, we discovered that stones with geodes are slightly lighter than solid rocks.
What color is a geode?
Look at the outer surface, which should be rough to the touch, and usually grayish or perhaps brownish. The interior of a natural geode is usually white to gray in bands, with perhaps crystals in the very interior, in the open space. USUALLY those are clear or white, occasionally they are purple or blue, or even pink.
What is the best indicator of what a rock is?
Typically locality is a great indicator of what the rock is. Do some research on the area, typically you will find others who have found similar rocks/minerals in the area. Forums and rockhounding websites are great tools.

Use a lapidary diamond-blade cutting saw to slice the geode open, or into halves. (Note that oil can damage the interior of some geodes.)
What color are geodes?
Geodes come in different colors. I've found rubies in some, which are red, and amethyst and others which are purple.
How to find the value of geodes?
The best thing you can do to accurately determine a geodes value is to take it to a professional certified gem appraiser. If you don’t have access to an appraiser where you live, a quick search on the internet should provide you with a number of appraisers. There’re plenty of people interested in buying and selling geodes. So much so that finding someone to give you a fair market value of your geode should not be difficult to do.
How Much Are Geodes Worth?
You might have found yourself in a similar situation. Perhaps being offered a nice sum of money for one of your special geodes, or perhaps your entire collection, only to turn the offer down because you felt it was worth much more.
What is the color of a geode?
The crystals displaying the deepest purple tones with strong color saturation are considered superior geodes. The quality decreases as the amethyst crystals lose their saturation and become lighter purple or reddish-purple hues. The second factor used in grading is the symmetry or the outside shape of the geode itself.
What crystals did the owners of the dig site crack open?
Together they cracked open the geodes he had found. Each of them displaying beautiful hidden displays of quartz and calcite crystals.
Why are geodes downgraded?
Since geodes are priced by weight, after grading its color and symmetry, a geode with very thick sidewalls or an extra heavy base would be downgraded since the extra weight is not adding anything to its beauty. Yet the weight is still being sold to consumer.
How big was the Geode bucket?
But inside one of those buckets was a geode quite a bit larger than all the others. The geode was probably 5 inches in diameter, while most of the other geodes he’d collected that day were between golf ball size and tennis ball size.
How much did the owner of the Geode offer the man?
Once they could see the ancient contents of the geode, they both could tell it was different. Immediately, the owner of the dig site offered the man $400 dollars for the geode. He would buy it from the collector on the spot.

How to cut thunderegg?
The goal of cutting a thunderegg is to reveal and highlight the inner geometry by cutting through any air pockets that exist and perpendicularly through the mineral layers. To accurately do this, one must estimate the inside layout based on how the egg formed. After cutting, sand and polish the flat surface with cerium oxide for the best shine.
How does water transport agate?
The water picks up the silicon from surrounding rock structures and transports it to the vicinity of the already hollow thunderegg (we will see how it becomes hollow later). It then is able to diffuse through the pores of the soft igneous rock on the outside into the inside.
Why is it important to have a way to make sure the egg does not move an inch during the cutting process?
The last of these is possibly the most important because it can have severe safety implications. You must have a way to make sure the egg does not move an inch during the cutting process. Some drop saws cannot fulfill this requirement because the egg has 360 degrees of rolling possibilities.
What does cutting perpendicular to the layer structure show off?
Cutting perpendicular to the layer structure will show off the geometry of the layers ideally.
Can you break geodes with a hammer?
If you have found, bought, or broken geodes open, you’ll know that it is generally regarded just fine to break a geode with a chisel and hammer. On the contrary, thundereggs are often much thicker and have a distinct difference from geodes that makes a chisel an inadequate tool for breaking them.
How are geodes produced?
In these situations the geodes are easily found and collected. Some geodes are produced by mining the host rock, but that method is difficult, costly, and often damages the geode. ADVERTISEMENT.
What Are Geodes?
Geodes are spherical to subspherical rock structures with an internal cavity lined with mineral materials. They have a durable outer wall that is more resistant to weathering than the surrounding bedrock. This allows the geode to survive intact when the surrounding bedrock weathers away. The mineral lining the cavity is often a scintillating druse of tiny quartz crystals underlain by multiple bands of translucent gray and white agate. Many are lined with more spectacular treasures.
What color are agate geodes?
Those with gray, white, or other less-interesting agate colors are often dyed bright blue, green, purple, red or other colors and then face polished to make them more appealing.
What is an unopened geode?
An unopened geode has the appearance of an uninteresting rock. They become much more interesting when they are opened and their internal crystals and agate bands become visible. And even though every crystal-lined geode is a wonder of nature, there are many things that can be done to make it into a more marketable product as well as enhance its value.
What is the name of the mineral that fills a geode?
Geodes are given a variety of names. The word “geode” is often preceded by the name of the mineral material which has filled the geode. “Agate geode” and “amethyst geode” are examples. The word “geode” might also be preceded by a geographic or stratigraphic name. “Keokuk geode” and “Brazilian geode” are examples.
What is the largest geode?
These small "lava tubes" produce some of the largest and longest geodes. Many cathedral geodes are branches of these lava tubes that later infilled with mineral material. Many of them have the geometry of long tree branches, being nearly a meter in diameter and many meters in length.
How big are Oco geodes?
They range in size between about 1/2 and 3 inches in diameter and formed in the vesicles of basalt flows that underlie parts of this region. Most Oco geodes have a thin agate rind, an open interior, and an interior druse of tiny sharp quartz points about 1/8 inch long.
