Wrap Around The Thigh
For hip or thigh discomfort: wrap the chain so the stone contacts the muscle and joint tissue.

Hold At The Elbow
For tennis elbow or tendonitis: loop around the elbow or hold the stone against the joint.

Wear On Wrist Overnight
For nighttime use: wear on the wrist while you sleep — passive, continuous frequency delivery.
The Joint Frequency Protocol
Every magnetic bracelet and copper bracelet in this category is designed to sit on your wrist. But your pain isn't in your wrist. Your knee is not your wrist. Your tendon is not your wrist.
The Terahertz Necklace was designed to go somewhere else. Loop it around the knee. Strap it to the thigh. Hold it at the elbow.
A field effect that doesn't reach the target tissue can't affect the target tissue. That's the only thing that changed.
The Joint Frequency Protocol 5 steps
What happens when you place it on the joint instead of the wrist
Put It On The Joint
Loop the chain around the knee, wrap it against the thigh, or hold it at the elbow. Placement on the painful area is the entire mechanism. Not on the wrist. On the joint.
Body Heat Activates The Stone
The silicon compound responds to body temperature. As it warms from contact with your skin, it begins emitting terahertz-range frequency — the band between microwave and infrared on the electromagnetic spectrum.
Frequency Reaches The Tissue
Unlike a bracelet 18 inches from your knee, a stone placed directly on the joint delivers frequency to the target area. Local frequency exposure is what researchers are studying — not whole-body or distal exposure.
Thermal Exchange Increases Circulation
The stone's unusually high thermal conductivity enables rapid heat exchange with the joint tissue. Improved local circulation is one of the mechanisms scientists are exploring in frequency-based pain research.
Test It First, Then Decide
Before you try it on your joint, put it on ice for 10 seconds. You will see it conduct cold significantly faster than it should. That's thermal conductivity in action — visible, reproducible, and verifiable before any pain claim matters.
What It's Made Of Lab-synthesized. Not dug up.
Six components. None of them mystical.

Knee pain for 3 years. One day on the joint.
I don't know what it did but I put on my knee for 1 day and my knee hasn't hurt since, that was one month ago. I was expecting nothing. I was wrong.
80% improvement in 4.5 hours.
My left thigh was sore and weak. I wore it on my thigh and my thigh feels better by 80% after 4.5 hours. After one night, it's all good. I put Terahertz on any part of my body now when it's uncomfortable.
"I was so skeptical. I was wrong."
I used something similar before and felt nothing. Didn't believe it. Then a friend showed me the ice test. I put it on my knee for a week. My knee stopped waking me up at night.
Elbow tendonitis — 3 years. Getting better.
I have had tendonitis in my elbows for a number of years from lifting weights. I have been wearing the terahertz for a month now and my elbows are getting much better. I think it increases blood flow to the area.
Elderly, sore knees. Now "almost all good."
I am an elderly person and have sore knees all year round. It's not easy to walk. I put it on my knees and I feel great now. It's almost all good. I ordered a second one.
Stopped sleeping pills after day 3.
I was troubled by sleep because of the joint pain. After wearing the terahertz necklace for two or three days, I started to get better sleep quality. Now I don't have to take sleeping pills as before.
Gym soreness after workouts. Works every time.
I get sore legs after going to gym. I put it on my legs after workout and it's very soothing. I use it on any body part that feels sore now.
Arthritis. Told surgery was the only option.
I hadn't been able to walk without a walker for 15 months due to severe arthritis in my hip. I had amazing pain relief and was shocked when the next morning I could walk upright.
A Note From the Team Behind Spirad
We built this product after spending two years in chronic pain communities, listening to what wasn't working.
The most common pattern: people who had tried magnetic bracelets, copper bracelets, compression sleeves — and concluded the entire category was useless. Not because frequency approaches don't work, but because the placement was wrong.
We are not selling hope. We're selling a specific, testable claim: place it on the joint, not the wrist. If that doesn't make a difference for you in 30 days, return it. We mean that.
Where It Comes From
Terahertz stone is a lab-synthesized silicon compound, manufactured in Japan.
It is not a crystal. It was not dug out of the earth. It was engineered in a laboratory to emit electromagnetic frequency in the terahertz band when activated by body heat.
The same base element — silicon — is what computer chips are made of. The difference is the crystal lattice structure, which determines what frequency the material emits.
This is not a spiritual product. It's material science.
Questions You're Probably Already Thinking
Why didn't my copper bracelet or magnetic bracelet work?
+
The most likely reason: it was on your wrist, not on the joint that hurt. A field effect that doesn't reach the target tissue can't affect the target tissue. The Terahertz Necklace is designed to go somewhere else — loop it around the knee, strap it to the thigh, hold it at the elbow. That's the only thing we changed.
How do I test if it's working before I put it on my joint?
+
Put it on ice for 10 seconds. It will conduct cold significantly faster than a room-temperature stone should. That's thermal conductivity — the same property that enables local frequency exchange with joint tissue. You can run this test before the stone ever touches your knee.
How long does it take to feel a difference?
+
Customers report different timelines: some notice a difference within hours of placing it on the joint. Others report improvement over days to weeks for chronic conditions. We don't guarantee specific outcomes — but we do back your investment with a 30-day money-back policy.
Can I wear it at night while I sleep?
+
Yes. Many customers wear the necklace on the wrist during sleep — the stone remains in contact with the skin and continues to exchange frequency. For targeted joint use during the day, loop the chain around the affected area.
Is this a crystal? Is it "healing jewelry"?
+
No and no. Terahertz stone is a lab-synthesized silicon compound — manufactured in Japan, not mined from the earth. The mechanism is thermal conductivity and electromagnetic frequency emission — not crystal energy or chakra fields. Its base material is the same class as a semiconductor.
What if I've already tried "frequency healing" and it didn't work?
+
If you wore it on your wrist and the pain was somewhere else — that's almost certainly why. Placement is the primary variable. The stone needs to be on the joint or the tissue that hurts. If you've done that and still felt nothing, return it within 30 days for a full refund.
What does the research actually say?
+
The NIH NCCIH reviewed 21 studies on electromagnetic frequency and joint pain. A 2024 eLife study investigated terahertz-range stimulation and neuropathic pain, describing it as a "new, non-drug method." A 2017 RCT tested frequency-emitting wearable material placed on the painful area with statistically significant results. We cite this research for context — not as a direct claim our product reproduces those results.
