Hunting Diamonds & Gemstones With A Metal Detector

Hunting for gems and diamonds can be a really fun and interesting outdoor activity for anyone to try. When traveling and visiting anywhere in the mountains, you’ll see a lot of stores that offer gemstone mining. In movies and television shows, you’ve probably seen a person scouring the beach with a metal detector for golden treasure.

Diamond Metal Detecting

Hunting for gems, gold, and coins is like playing a geological lottery. It’s exciting but one person could spend hours searching endlessly and find nothing while another person can randomly happen upon a diamond in the park.

Even if you don’t strike gold, gem hunting can still be a rewarding hobby to pick up. You get to spend time outdoors, learn about geology, and hang out with friends that share your interest. You can make it a serious endeavor or you can become a collector. Just as there are many forms of searching for gems, there are so many ways to enjoy gems.

The most interesting and rewarding way to hunt for gems is with a metal detector. They make it easy to find unknown treasure below surfaces, adding to the excitement of gem hunting.

How To Hunt For Diamonds & Gemstones

If you’re using a metal detector you can’t expect to find more than coins and metal jewelry. If you want to use your metal detector to find gems, diamonds, or pearls, you have to search for indicators around the precious stone. From there, you as the prospector have to use your intuition to determine where the gemstone is.

The indicators to look for include glassy green olivine, black picroilmenite, chromium garnets, and magnetite. These are the same minerals that indicate gold is nearby so if you have a gold metal detector and know what to look for you can find diamonds and other gemstones.

The Best Locations To Find Diamonds & Gems

Before setting out on your treasure hunt, be sure to look for sources that will tell you about sites that might be fruitful. These sources could be local town plans, mining reports, or just old residents.

Be aware that the hardest gem to find in the United States is the diamond. Any diamond found in the US is probably prospected by those who gem hunt as a hobby. They’ll probably find it affixed to jewelry since diamonds are usually mined in South Africa. Don’t go somewhere and expect to find natural diamonds. Here are some places that you can find some gems and coins.

1. Parks.

Parks can be great places to find treasures, especially since they often host concerts, fairs, and circuses. Before going to a park, be sure to seek permission to bring your metal detector on the premises. Some local authorities don’t allow for metal detectors without a license and you risk the chance of getting it confiscated.

2. Fields.

Fields of grass are a good option for treasure hunting, especially since land has been used for many activities in the past. If you research a history of a field you may find it used to be camps, a trading site, training ground, or even a burial site. With proper research, you can have an idea of what you’re going to find.

Farmers’ fields are even better than just plains of grass and they are one of the most popular places to search for gems and jewels with a metal detector. When farmers plow the earth, it moves the dirt around and brings the buried treasure underneath closer to the surface. When going to a farmer’s field, get permission from the farmer and come to terms with how you’d split any treasure you might find.

3. Woods and Footpaths.

People walk on footpaths and woods almost every day and they drop all kinds of goodies. They’re perfect places to find treasure. Woods are regarded as public, though it is not public land. What it means essentially is that the owner of the land has given right of way to the public.

To be safe, try to identify who the owner is and make sure it’s okay with them to use your metal detector.

How Metal Detectors Work

How a metal detector works depends on what type of metal detector it is, but there is easily explainable science behind the simpler ones. On a metal detector, there is a coil of wire, known as the transmitter coil, that wraps around the circular head.

A magnetic field is created when the electricity goes through the transmitter coil. When you sweep the metal detector across the ground, the magnetic field goes along with it, and if it passes over a metal object the atoms in the metal induce some electrical activity.

This cause another magnetic field to appear around the metal object and that’s what your metal detector picks up.

Bottom Line

You want to have fun while searching for gems, coins, diamonds, and gold. To do this you need to find the best metal detector for you. Factors to keep in mind include the metal detector’s sensitivity, discrimination, calibration, radar, coil size and shape, extra technology, pinpoint mode, and depth indicator. Be sure to read radar and pinpointer reviews and do extra research to make sure you’re getting the right metal detector.
