Description
A precision-cast bar pendant finished with a polished layer of real copper. A micro-thin clear coating helps slow initial surface change. The passive, magnet-free construction contains no battery or powered electronics.
Why copper?
Copper is one of the most electrically conductive metals and is widely used in electromagnetic compatibility and shielding applications. The Quantum™ Necklace incorporates a polished layer of real copper into a slim design made for everyday wear.
How to wear
Adjust the Adult chain from approximately 18 to 20 inches. Wear the pendant against the skin or over clothing; direct skin contact is not required. Remove it before showering or swimming.
Shipping and returns
Free standard shipping within the U.S. and Canada. Returns are available within 30 days, subject to the return policy.
Connected routines
Designed to move through a connected day
Phones, Wi-Fi, laptops, Bluetooth accessories, and other electrical devices are part of the places where we work, travel, exercise, and unwind. The Necklace is designed as a passive wearable for those routines, with nothing to charge, activate, or pair.

Why copper?
Copper’s role in electromagnetic shielding
Copper is one of the most electrically conductive metals. When incorporated into an appropriately designed structure, it can help reflect and absorb electromagnetic energy.
Naturally conductive
Copper carries electrical current exceptionally well, making it a foundational material in electrical and electromagnetic engineering.
The design matters
Copper sheets, films, meshes, and enclosures interact with electromagnetic fields differently. Coverage, continuity, openings, placement, and frequency all influence the result.
Used throughout modern electronics
Copper is used in cables, circuit boards, shielding films, equipment enclosures, and other systems designed to help manage electromagnetic interference.
BEAM™
Material + geometry + intended placement
BEAM™ is Conscious Copper’s design framework for bringing these elements together across its product range. In the Necklace, it takes shape through the real-copper layer, slim bar geometry, and adjustable chest-worn design.

In engineering applications, a continuous copper shield can reflect and absorb electromagnetic energy. Select each view to compare the same illustrative field path with and without the shield.

How this relates to the Necklace
Illustrative materials-science comparison—not a test or performance representation of the Quantum™ Necklace.These principles help explain why copper is used in electromagnetic engineering. The Quantum™ Necklace incorporates a polished layer of real copper into Conscious Copper’s passive wearable design.
Thin copper structures can still matter
A published 2022 laboratory study reported substantial shielding from a continuous, high-conductivity copper-based film at 3.5 GHz under defined conditions.
Review the study ↗Openings change the result
Research on continuous and slotted copper RF shields found that introducing slots materially reduced shielding around those openings.
Review the study ↗Geometry is part of the mechanism
A 2024 copper-mesh study showed that enlarging mesh openings changed measured shielding effectiveness across the tested microwave range.
Review the study ↗What this research does—and does not—tell us
It supports: copper’s established relevance to electromagnetic shielding engineering, and the importance of conductivity, continuity, geometry, coverage, frequency, and measurement conditions.
It does not establish: attenuation, exposure reduction, body-level effects, or protection provided by the finished Quantum™ Necklace. Those require finished-product testing in the intended configuration.

Care and finish
Keep the copper finish looking its best
The clear protective coating helps slow initial tarnishing and surface change, but it does not permanently prevent signs of wear.
Remove before showering, swimming, or soaking.
Sweat, skin oils, lotions, perfume, soap, and cleaners can accelerate wear.
Use a soft, dry microfiber cloth. Avoid polish and liquid cleaner.
Store it in its protective sleeve, away from harder jewelry.

Quantum™ Necklace FAQ
What is the Quantum™ EMF Necklace?
The Quantum™ EMF Necklace is Conscious Copper’s passive, copper-finished wearable for everyday life around phones, Wi-Fi, Bluetooth devices, laptops, and other common sources of EMF. It contains no batteries, magnets, powered electronics, or app-connected components.
Why is copper relevant to EMF?
Copper is one of the most electrically conductive metals and is widely used in electromagnetic compatibility engineering. Properly configured copper sheets, films, meshes, coatings, and enclosures can help attenuate electromagnetic transmission under controlled conditions.
Does copper block EMF?
Copper can provide substantial electromagnetic shielding when it forms an appropriately designed conductive structure. The result depends on frequency, thickness, geometry, openings, electrical continuity, coverage, placement, and test conditions. Copper content alone does not establish that every copper object provides the same effect.
Do the cited copper studies test the Quantum™ Necklace?
No. The referenced studies concern purpose-built copper films, meshes, shields, and other conductive structures. They provide context for why copper is relevant to electromagnetic engineering but do not establish the attenuation, exposure reduction, or protection provided by the finished Necklace.
How is the Necklace intended to be used around EMF?
The Necklace is designed as a passive wearable for EMF-conscious routines involving common connected devices and electrical sources. It incorporates a polished layer of real copper into a slim, chest-worn design.
What is BEAM™?
BEAM™ is Conscious Copper’s design framework for bringing material selection, physical geometry, and intended placement together across its product range. In the Necklace, this includes the real-copper layer, slim bar-shaped pendant, and adjustable chest-worn design.
Are shielding and grounding the same thing?
No. Copper is used in both electromagnetic shielding and electrical grounding applications because it is highly conductive, but these are different engineering concepts. Conductivity alone does not establish that a wearable grounds electromagnetic energy away from the body.
Does the pendant need to touch my skin?
No. Wear the pendant against the skin or over clothing based on comfort and personal style. Direct skin contact is not required.
Can I exercise, shower, or swim while wearing it?
The Necklace is suitable for everyday wear and light exercise. Wipe it with a soft, dry cloth after sweating. Remove it before showering, swimming, or soaking in chlorinated or salt water.
What should I know about metal sensitivity?
Individuals with known nickel or base-metal allergies should exercise caution. People with highly sensitive skin should wear the pendant over a shirt rather than directly against bare skin. Discontinue use if irritation develops.
