🧭 How to Identify a Genuine PEMF Mat
It can be overwhelming when searching for a PEMF mat for the first time. With so many brands and claims online, how do you know which one you can trust?
Over the last few years, gemstone-style PEMF mats have flooded the global market — especially from large-scale Asian manufacturers that also supply products on Alibaba and similar platforms. This page will help you understand the differences and quickly identify imported gemstone mats that are marketed as PEMF systems.
Many gemstone mats are mass-produced and rebranded by marketing companies. A single factory design can appear under dozens of brand names, each with its own logo and story — but internally, they are often identical.
For example, a gemstone mat purchased directly from Alibaba for around $200 USD may be re-labelled and sold online for $1,000 to $2,000 USD, sometimes with claims of “advanced PEMF technology” that are not supported by technical data.
It’s important to recognize the marketing language these products use. Typical keyword phrases include:
PEMF • Negative Ions • Tourmaline • Amethyst • Gemstones • Far Infrared (FIR) • Photon Lights • Crystal Therapy • Chakra Healing
If you see several of these terms together — without clear engineering specifications or waveform data — you’re likely looking at a gemstone mat with basic heating elements, not a genuine pulsed electromagnetic field (PEMF) system.

Behind the Scenes:
How Mass-Produced Gemstone PEMF Mats Are Manufactured
Most gemstone-style PEMF mats are mass-produced in large Asian factories, where identical parts are assembled in bulk and later re-branded and sold under various names. These production lines prioritise volume over quality, resulting in many mats that look different on the outside but are built the same inside. By the end of this webpage article, you’ll be able to spot re-branded Asian gemstone mats and red-light mats instantly — and know exactly what’s inside them.
Example of a typical factory in Asia where multi-therapy gemstone PEMF mats are assembled for many different brand names.
Over 95% of all multi-therapy PEMF mats — including those with gemstones, red lights, negative ions, and far-infrared – are produced in the same style of factories across Asia. These facilities often manufacture for multiple brand names, simply re-labeling identical mats with different logos and packaging.
Inside these factories, the production lines typically assemble large batches of identical mats using pre-fabricated heating grids and ferrite rod coils, with minimal quality control or individual calibration.
Understanding how and where these devices are made helps reveal why many low-cost PEMF mats share the same internal components, regardless of the brand name printed on top.
The Process of Selling Online PEMF Gemstone Mats
While these mats may offer heat and light features, they usually do not use true engineered PEMF technology. Instead, they often rely on gemstones, basic electronics, and LED lights to create the appearance of PEMF benefits. This supply-chain model explains why many similar-looking mats appear under different brand names worldwide.
This information helps consumers understand the difference between re-branded gemstone mats and professionally engineered PEMF systems designed with medical-grade technology standards and real electromagnetic coil and far infrared architecture.
Understanding Gemstone-Style “PEMF” Mats (Made in Asia)
Many low-cost gemstone-style PEMF mats sold online are mass-produced in Asia (primarily China) and then re-branded and marketed as premium wellness systems. These mats are typically purchased from factories for around $100–$200 USD, a logo is added, and then they are resold online for $800–$2,000+ under different brand names
PEMF Coils vs Ferrite Rods - Whats Inside Matters
COMPARE THE COILS
Most imported gemstone mats use AM/FM radio antenna ferrite rods — components originally designed for low-frequency radio receivers, not pulsed electromagnetic field therapy. These small rods create a very limited field area and lack the depth required for full-body PEMF effects.
In contrast, PEMF.inc systems use large, precision-engineered copper coils. These large, circular, genuine coils deliver a broad, uniform electromagnetic field, ensuring proper cellular stimulation and effective full-body coverage — the hallmark of authentic German PEMF technology
Coil Diameter and Why it Matters
The coil diameter plays a crucial role in determining the power, efficiency, and overall performance of a PEMF mat. The thickness and quality of the copper wire directly affect how efficiently the system can generate a stable magnetic field and deliver consistent pulsed electromagnetic therapy.
In many imported gemstone mats produced across Asia, the internal coils are made from very thin and fragile wire. This fine copper has higher electrical resistance, which restricts current flow and reduces the magnetic induction strength — resulting in weak, inconsistent, and short-lived pulses. Such designs may look impressive from the outside, but internally they lack the engineering to deliver genuine PEMF performance.
By contrast, PEMF.inc German-engineered coils use thicker, precision-wound copper wire to maintain strong current flow, consistent induction, and reliable field strength. These robust coils produce a higher and more uniform magnetic flux density across the mat surface — leading to improved effectiveness, greater energy transfer, and long-term reliability.
As the saying goes, seeing is believing. The comparison image below clearly shows the difference between a thin imported wire and our high-grade German PEMF coil. The visual contrast highlights how coil thickness and engineering quality directly determine a mat’s performance and lifespan.
Always compare PEMF coil thickness, build quality, and verified magnetic-field strength before investing in a PEMF mat. These details reveal the real engineering behind the system — not just the marketing claims.
Exposed: The $0.60 Ferrite Coil Hidden Inside Many Gemstone Mats
Many imported gemstone-style PEMF mats use low-cost ferrite coils — the same type found in AM/FM radios and low-frequency consumer electronics. These small, pre-wound radio coils cost less than USD $0.60 each in bulk and are not designed for PEMF therapy applications.
Unlike true PEMF-specific copper induction coils, ferrite coils generate minimal magnetic field strength and lack the ability to deliver consistent pulsed electromagnetic frequencies across the body. This exposes the clear difference between cheap mass-produced mats and engineered PEMF systems built for performance and reliability.
Red Light Therapy or Red Christmas Tree Lights ?
Is Red Light therapy the same technology being used in Gemstone mats. See photos inside the mat when opened.
What’s Really Inside the Red Light Gemstone Mats?
When we opened several imported gemstone mats advertised as offering red light therapy, the internal components revealed something very different from professional-grade light therapy technology. Inside, we found small red plastic LEDs connected with thin silicone wiring—similar to what’s used in low-voltage decorative or Christmas-style lighting. These lights emit a faint red glow but lack the wavelength strength or calibration required for therapeutic near-infrared (NIR) or red light benefits.
True red light therapy devices use specific nanometer wavelengths (typically between 630–850 nm) that penetrate tissue and support cellular function. The lights inside these mats are for visual appearance only, providing no measurable therapeutic or wellness effect on the body.
At PEMF.inc, our goal is to help consumers identify the difference between real red light therapy systems and low-cost LED imitation mats—so you can make informed choices about your wellness technology.
Silicone Heating Wires Found Inside Imported PEMF Gemstone Mats
This image shows the type of silicone heating wire commonly found inside mass-produced gemstone and red-light mats imported from Asia. These wires are often marketed as “Far Infrared” technology, but in reality they function simply as basic electric heating elements, similar to those used in electric blankets and seat warmers.
Unlike genuine Far Infrared emitters, these silicone wires provide only surface heat rather than deep infrared resonance. This knowledge allows consumers to separate true engineered wellness systems from mass-produced heating mats found in PEMF multi-therapy gemstone mats.

The Hidden Truth About “Far Infrared” Gemstone Mats
Most imported “Far Infrared” gemstone mats simply use cheap silicone heating wires under a layer of gemstones. While the marketing claims suggest deep, therapeutic far infrared energy, the reality is that these wires only generate basic surface heat—not the stable, body-penetrating wavelengths produced by true far infrared materials.
The image below reveals what’s really happening beneath the surface, helping consumers spot the difference between real FIR technology and standard electric heating mats disguised as advanced wellness systems.
Why Carbon Fibre Is the Superior Choice for Far Infrared Heating
Carbon fibre is regarded as the premium material for Far Infrared (FIR) heating technology. Unlike the silicone heating wires often found inside imported gemstone mats, carbon fibre produces a smooth, even distribution of gentle Far Infrared warmth across the entire mat surface.
This advanced design provides stable heat emission, longer life span, and far greater energy efficiency. The structure of carbon fibre allows it to emit deep, consistent infrared wavelengths that feel natural to the body — not the surface-only heat generated by simple electric wires. This is why PEMF.inc German-engineered systems use genuine carbon fibre elements for authentic, reliable Far Infrared performance
What’s Really Inside Imported Gemstone Mats? Crystal Therapy or Plastic Parts?
Many imported gemstone mats are advertised as containing genuine crystals or gemstones, but when opened and inspected, the materials inside often tell a different story. Instead of natural crystal minerals, several models reveal factory-molded plastic discs that resemble shirt buttons or synthetic pellets. These components are inexpensive to manufacture and provide no measurable Far Infrared or energetic properties associated with true gemstones.
This comparison highlights the importance of verifying what’s actually inside a mat before purchasing. At PEMF.inc, we focus on transparency and authentic engineering, helping consumers identify real materials and genuine wellness technology.
Inside the Imported Gemstone Mats – What’s Hidden Beneath the Fabric
When the fabric layers of many imported gemstone mats are opened, it becomes clear how the round “crystal” pieces are inserted. These discs are placed from the inside of the mat, fitted into stitched pockets that make them appear as gemstones from the outside. However, closer inspection often shows molded plastic components rather than genuine crystal minerals.
The manufacturing style focuses on appearance rather than performance, with no real Far Infrared or energetic function. At PEMF.inc, we encourage buyers to look beyond surface design and understand the true materials and construction quality behind their wellness mat investment.
Do Imported Gemstone Mats Really Produce Negative Ions? Our Test Results
Many imported gemstone or multi-therapy mats are advertised as generating negative ions for wellness benefits. To verify these claims, we tested several models using a professional negative ion meter. The readings showed no detectable negative ion output, indicating that these mats do not produce the effect claimed in their marketing.
The internal components are typically basic heating wires and LED lights, without any ion-generating materials or circuits. Consumers can perform the same check using an ion tester at home. At PEMF.inc, we focus on transparency and real engineering—helping you understand the difference between genuine technology and marketing gimmicks.
The Importance of a Signal Generater
A signal generator is needed in a PEMF machine to create pulsed magnetic fields. Electricity from the PowerPoint in the wall socket to the signal generator converts electricity to pulsed electromagnetic fields, which radiate through the body mat or pad applicators via the copper coils. However, the cheaper gemstone mats do not use a signal generator.
Without any built-in frequency generators at the incoming mains current (e.g 50HZ in Europe and 60 HZ in North America) is “chopped” unfiltered and without control to generate frequencies. Without a frequency generator, the product will have no targeted control over the energy field and no scientifically supported therapeutic effect.
CONCLUSION
✅ Why Transparency and Testing Standards Matter
Many imported PEMF-style gemstone mats provide little to no verified technical information about their internal design, components, or electronics.
Most listings omit key performance data — such as waveform type, frequency range, pulse generation, or independently tested magnetic-field intensity (flux density and field strength).
Associates who have visited manufacturing plants in Asia report that many staff and resellers cannot explain or demonstrate how their machines produce PEMF signals — or even how to test for the important PEMF parameters.
These encounters revealed a disconnect between sellers and manufacturers, highlighting how easily misinformation spreads through rebranded, imported mats.
Nearly all systems in this category lack certified quality management and are not produced to medical-grade manufacturing standards, meaning performance and safety claims cannot be independently verified.
At PEMF.inc, we believe seeing is believing.
We’ve purchased and physically opened multiple imported gemstone mats to reveal their internal wiring, coils, and circuitry — so you can see what’s truly inside, not just what’s shown in marketing photos.
