We have previously talked about gem hunting, but we have not discussed the steps as to how to approach the prospecting for gemstones, so let’s get right into how you start your gem-hunting adventure:

Research Your Locations

Different types of gemstones are found in a variety of regions, so it’s important to identify areas where the stones you’re interested in are found.

Start with the Ineternal Gem Society. They can provide you with some of the top locations around the country where you can dig for gemstones.

Make Sure You Have the Right Equipment for Your Gem Search

Depending upon the location you select, they should be able to provide you with the necessary tools for your hunt, most probably for a fee, but you could bring your own equipment as well. That would consist of a pair of gloves, a shovel, a bucket, a screen or sifter, and a magnifying glass. Additionally, when you are there, ask for a gemstone identification guide.

Ever gone bird watching?

If yes, then you know that you have to travel to a certain spot of a particular destination to view a specific species of bird. To find the right destination for bird watching, one has to find out the species’ habitat, migration patterns, food choices, etc.

Knowing these things will help you figure out the location where a particular species of bird is likely to be found. You cannot simply wander around the forest in the hope of finding the types you are looking for; it would be nothing more than wasting time.

Experts say that gem hunting is much like bird watching. You most likely will not find minerals dug in the soil outside your home; however, the practical approach is to first research the areas where the gems are naturally found and then use the right technique to access the deposits.

For example, since diamonds are formed as a result of extreme pressure, they are either found deep inside the earth, in areas where various geological processes have pushed the mantle rocks from the depths of the earth to the surface, or alongside the rivers that flow from such areas.

Similarly, if you are looking for malachite, you have to look for it near copper and limestone deposits.

The occurrence of gemstones may also vary across countries, depending upon their geological processes, volcanoes, storms, and earthquakes, as they cause shifts in the tectonic plates and bring the buried bedrock to the surface of the earth.

Methods for Gemstones Mining

From basic to advanced, there are various mining methods. They include:

  • Underground Mining

When hunting for your stones is done within the pipe and alluvial deposits, it is called underground mining. The methods used for underground mining are:

  • Block caving
  • Tunneling
  • Chambering
  • Open Cast Mining

Open-cast mining uses different techniques. Here removal of the upper layer of rocks is required in order to reach the bedrock, which is buried deep inside the earth that contains the gems. Any of the following methods are used to excavate gems from the deepest layers of the earth:

  • Terrace Mining
  • Pit Mining

Open-cast mining methods are widely used in various parts of the world including the United States, Sri Lanka, Brazil, and Myanmar. etc.

  • Sea Mining

Sea mining, marine or undersea mining, as they are alternatively called, is used in areas where marine deposits are present.

  • River Digging

As evident from the name, river digging is performed in and around rivers and lakes to excavate the gems that have been buried in the river soil and rocks naturally, by the water current or geological processes over time. It can further be classified into two types:

  • Wet Digging
  • Dry Digging

Gem Hunting Tools

As with any other specialized task, you cannot expect to have a successful gem-hunting experience if you don’t have the right tools and equipment.

For example, there is no point in going fishing without a fishing tackle and/or bait. It is highly unlikely to catch a fish with your hands. Similarly, searching for gemstones without the proper gem-hunting tools is nothing more than wasting your time. Tools for gem hunting are easily available at affordable prices, which means that even occasional hunters can easily buy them without exceeding their budgets.

For gem hunting, you would need the following basic tools:

  • Shovel
  • Rock Hammer
  • Magnifying lens
  • Bucket and collection bags
  • You may need some specialized equipment to excavate some particular types of gems, such as a metal grid frame for screening, a pan for gold, etc
  • Permanent markers for labeling

For your safety and comfort:

  • Wear comfortable clothes and shoes
  • Apply insect repellent and sunblock
  • Wear goggles
  • A GPS device or map to find your way
  • Water
  • Hat
  • Gloves
  • Walkie-Talkies for communication

There is More Than One Method for Gem Hunting

You should research the different methods employed when looking for your precious stones. Some of the most popular are: 

  • Hydraulic Mining, where jets of water are used to loose the rocks from the dirt, 
  • River Panning is where you essentially wash away the gravel to find the minerals, 
  • Open Pit Mining, where you physically remove rocks, possibly in a quarry to search for the gems.

But this just scratches the surface (pun intended). Do some research to find the best method you prefer.

Learn Gemstone Identification

Familiarize yourself with the characteristics and properties of the gemstones you’re hunting for. Look for distinguishing features like color, luster, hardness, and crystal structure. Using a mineral identification guide or app can help determine the gemstones you find.

 

Kepler-186f: Is This an Earth Clone?

Discovery

Johannes Kepler was a 17th-century German astronomer who discovered the systematic rotation of planets around stars, called the Laws of Planetary Motion, it states the following:

  • All planets revolve around the Sun in elliptical orbits.
  • A radius of the planets moves out in equal areas and in equal lengths of time.
  • The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun. (You don’t have to concern yourself with this law for our article here).

Being that Kepler was a cosmologist who focused his studies on planets, it is fitting that NASA named a spacecraft after him which looks for planets outside of our solar system, called exoplanets.

Specifically, the Kepler Space Telescope is designed to locate exoplanets that exist in the habitable zones, also called the Goldilocks Zone, where conditions are not too hot and not too cold for life as we know it, and which subsequently provides the ingredients for the possibility of liquid water on the planet’s surface. Liquid water is the ingredient that sets the stage for life to cultivate. Water can be found on many planets, some in the form of solid ice, but without water, the possibility of life to develop is minute. 

A Perfect Find!

The Kepler spacecraft has not disappointed us. It has located numerous planets that fit this habitual category. Not the least is Kelper-186f, which not only contains an abundance of water but is also similar to Earth in significant ways.

It is an exoplanet that orbits the star Kepler-186 in the constellation Cygnus and is only 500 light-years away from Earth. A mere ‘drop of the bucket’ in distance when considering how incomprehensibly large the universe is.

Kepler’s Sun

Numerous methods are employed to locate these planets. The Kepler telescope uses the transit method which finds celestial objects by observing the periodic dimming of their star’s light as the planet passes in front of it. In other words, it measures changes in the lightness of stars where periodic dips in brightness occur. 

Kepler-186f’s star is an M dwarf, which is a red dwarf. Red dwarfs are smaller and cooler than our Sun, and this star is about half the size and half the temperature of our Sun.

The Planet 

This orbital body is approximately the same size as Earth, making it one of the first Earth-size, habitable-zoned planets discovered outside of our solar system.

The time it takes Kepler-186f to complete one orbit around its star is approximately 130 Earth days. This is shorter than Earth’s orbit around our sun, which is 365 days, but this does not diminish the possibility of life existing there.

Future Research

Due to the current limitations of technology at this time, the Kepler-186f’s distance, although only 500 light years away, our ability to obtain more detailed information remains a significant challenge. 

So further advancements in observational planetary technology are needed to acquire the specifics of distant worlds such as Kepler-186f, but we should look forward to obtaining more information about this exoplanet as it has so much to offer considering its close resemblance to our planet and other physical factors that exist there. 

Conclusion

Kepler-186f may not be a perfect match to Earth, but we should not expect it to be. The existence of life is still a good possibility and if we expand our horizons a bit more, we can consider the potential of intelligent life as well; although these beings might not look exactly as we do.

Despite the planet’s location in the habitable zone, several factors could affect a being’s habitability there. One circumstance refers to the planet’s closeness to its red dwarf sun, which might expose it to increased stellar activity (sun spots, solar flares, plasma eruptions) that are greater than from our sun.

This could impact the planet’s atmosphere and surface conditions, resulting in life forms that could have much thicker skin than us, in order to avoid the dangers associated with ultraviolet radiation and x-rays common from stellar actions.

Even a slight change in any external factor on the planet (temperature, light exposure, gravitational pull, etc) may make their appearance look different from us in one way or another. But does it matter? We should welcome them anyway, or should we?
