While pure gold and silver won’t stick to your magnet when fishing (they’re diamagnetic), you can still uncover precious treasures indirectly. Look for magnetic components in jewelry like clasps and settings, or gold-plated items with magnetic cores. Target high-traffic areas like bridges and historical sites where mixed-metal valuables accumulate. Always examine retrieved magnetic items carefully for attached precious metals. With the right equipment and technique, those elusive treasures aren’t beyond your reach.
Key Takeaways
- Pure gold and silver are diamagnetic and won’t stick to magnets directly, but can be found with magnet fishing indirectly.
- Look for jewelry with magnetic clasps or settings that contain non-magnetic precious metals attached to them.
- Target historical sites, bridges, and docks where valuable mixed-metal items are more likely to accumulate.
- Search retrieved ferromagnetic debris for attached gold or silver components that would otherwise remain undiscovered.
- Gold-plated or silver-plated objects with magnetic cores can be successfully retrieved through magnet fishing.
The Science Behind Magnetism and Precious Metals
When delving into the world of magnet fishing, understanding the fundamental principles of magnetism and how they interact with various metals becomes essential for success. Your magnet primarily attracts ferromagnetic elements like iron, nickel, and cobalt—metals with strong magnetic properties that readily respond to magnetic fields.
Unfortunately for treasure hunters, precious metals like gold and silver are diamagnetic, meaning they’re actually weakly repelled by magnets. This principle is the basis for the magnet test used by investors to verify precious metal authenticity. Platinum and palladium exhibit paramagnetism, showing minimal attraction. This explains why you won’t directly catch pure gold or silver with your magnet.
The good news? Some metal treasures contain ferromagnetic alloys or components. Pure gold is classified as a diamagnetic material with a weak repulsive force towards magnets. Temperature, electron configuration, and alloy composition all influence magnetic behavior.
There’s still hope for treasure hunters—many valuable finds contain magnetic metals alongside precious materials.
While you won’t pull up pure precious metals, you might discover items where they’re combined with magnetic materials.
Why Gold and Silver Don’t Stick to Your Fishing Magnet
The excitement of pulling up a magnet heavy with finds can sometimes lead to disappointment for treasure hunters hoping to discover gold and silver.
Here’s why these precious metals elude your magnet fishing efforts: gold and silver are diamagnetic materials, meaning they actually repel magnetic fields slightly rather than being attracted to them.
Unlike ferromagnetic metals like iron or nickel, these valuable metals lack unpaired electrons that would allow them to stick to your magnet.
Testing with magnets is an effective method to identify fake metals that might be masquerading as gold or silver.
If you find a supposedly gold or silver item that’s attracted to your magnet, you’ve likely discovered an item with ferromagnetic impurities or a counterfeit.
Pure precious metals will never cling to your fishing magnet, regardless of its strength.
When subjected to external magnetic fields, the electron orbits in gold and silver merely rearrange temporarily without creating any lasting magnetic properties.
Don’t be discouraged though—genuine treasures often rest near magnetic objects, waiting for your keen eye to spot them.
Clever Ways Magnet Fishing Can Still Uncover Gold and Silver
Although pure gold and silver won’t stick to your fishing magnet directly, clever magnet fishing enthusiasts have developed numerous strategies to uncover these precious metals from watery depths.
Many valuable items contain magnetic alloys alongside precious metals—jewelry clasps, watch components, and settings often incorporate ferrous materials that will respond to your magnet.
Target bridges, docks, and historical spots where people frequently lose mixed-metal valuables. When you retrieve magnetic debris, examine it carefully for attached gold or silver components. Pure gold remains completely unaffected by even the strongest magnetic fields due to its stable atomic structure.
Use your magnet fishing as a first step in treasure hunting by clearing ferrous obstacles, then follow up with manual searching around these hotspots.
Remember that gold-plated or silver-plated objects with magnetic cores will readily attach to your magnet, potentially leading to significant finds despite the non-magnetic nature of pure precious metals.
Consider fishing from kayaks or canoes to reach areas with potentially higher concentrations of lost valuables that might contain precious metals.
Essential Magnet Fishing Equipment for Treasure Hunters
Successful treasure hunting with magnets requires specific equipment engineered for retrieving metallic objects from underwater environments.
Your primary tool is a neodymium magnet, available in various types: single-sided, double-sided, or 360-degree configurations. Choose at least N42 grade with 1000+ lbs pull force for serious hunting.
Pair your magnet with marine-grade rope materials like polyester or nylon (65-100 feet length, 6-8mm thickness) that resist water damage and abrasion. Secure everything with heavy-duty locking carabiners rated above 5500 lbs—aluminum versions work best with 360° magnets to prevent sticking.
Don’t overlook protection: cut-resistant gloves, sturdy footwear, and durable containers for your finds. The five-gallon bucket is an ideal storage solution for transporting your gear and treasures safely.
Apply threadlocker to eyebolts for additional security when pursuing larger treasures.
The most productive hunting occurs at historical sites with past human activity, where metal items have accumulated over decades beneath the water’s surface.
Identifying Real vs. Fake Precious Metals in Your Finds
When you’ve hauled up metallic treasures from murky waters, determining their composition becomes your next critical challenge. The neodymium magnet that just captured your find becomes your first counterfeit detection tool.
Pure gold and silver aren’t magnetic—if your item sticks, it’s likely not precious metal.
For effective magnetic testing of your discoveries:
- Use a strong neodymium magnet directly against each component of your find.
- Note any attraction—even slight resistance suggests ferromagnetic metals are present.
- Test separate parts individually, as clasps may contain different metals than the main piece.
Compared to common magnets, neodymium magnets offer superior strength for detecting even minimal amounts of magnetic materials in potential counterfeits.
Remember that magnetic testing is preliminary—non-magnetic metals like copper or aluminum aren’t precious either.
For conclusive identification, complement this test with visual inspection for hallmarks and wear patterns.
For gemstone accessories in your finds, a powerful magnet can help identify garnet pendants by observing any chain movement when brought near the stone.
Remarkable Gold and Silver Discoveries From Magnet Fishing
While magnet fishing in historic waterways, you’ll occasionally encounter remarkable gold and silver treasures including coins from sunken vessels that became trapped in ferromagnetic debris.
You might retrieve jewelry with magnetic clasps or components that allow your magnet to pull up precious items otherwise beyond reach.
Perhaps most exciting, you could discover submerged safes containing gold caches, as happened in Saginaw, Michigan, where a magnet fisher pulled up an entire safe filled with valuable gold items.
Coins From Sunken Vessels
Beneath murky waters worldwide lie thousands of shipwrecks harboring remarkable gold and silver coins waiting to be discovered through magnet fishing.
These sunken treasures offer archaeological evidence of ancient trade routes while substantially increasing in numismatic value when bearing specific dates and mint marks.
You’ll find magnet fishing particularly productive near historical sites where vessels once traveled.
Ferrous coins retain their magnetic properties despite prolonged submersion, making them retrievable with powerful neodymium magnets.
For maximum recovery success:
- Target urban waterways with proximity to historical settlements
- Use magnets with combined pull force exceeding 1,600 pounds
- Focus on areas near old bridges, piers, and ruins
Historical shipwreck coins provide unique insights into economic systems of past eras, with documented cases of significant precious metal recoveries occurring in places like Sydney Harbour and Lake Erie.
Jewelry With Magnetic Parts
Beyond shipwreck coins, many magnet fishing enthusiasts have made stunning discoveries of gold and silver jewelry that wouldn’t seem retrievable with magnets at first glance.
While pure precious metals aren’t magnetic, jewelry construction often incorporates magnetic alloys in clasps, posts, and settings.
Your fishing magnet can retrieve golden watches with steel mechanisms, sterling silver earrings with ferrous posts, and even gold rings with mixed-metal settings.
Documented expeditions have yielded treasures valued at $115 per session, including 10-karat gold rings and various silver pieces.
This magnetic attraction serves as an effective field test—anything that clings to your magnet isn’t pure gold but contains alloy components.
The presence of these magnetic elements in otherwise non-magnetic precious metals creates the perfect opportunity for you to recover valuable items that would otherwise remain hidden underwater.
Safes Containing Gold
The most exhilarating finds in the magnet fishing community often come from steel safes lurking beneath murky waters.
These underwater safe discoveries can yield substantial treasures, as evidenced by remarkable finds in Saginaw and Amsterdam where safes contained genuine gold jewelry, silver items, and valuable coins.
When employing safe retrieval techniques, you’ll need:
- Strong neodymium magnets capable of lifting 50+ kg weights
- Reinforced fishing lines that won’t snap under pressure
- Partners to assist with extraction, especially for deeply embedded safes
Remember that reporting your finds to authorities is essential, particularly when recovering valuables.
The thrill of pulling a heavy safe from murky depths is unmatched, especially when that distinctive glimmer of gold appears inside your recovered treasure.
