What 90 Days of Wearing Three Different Energy Necklaces Actually Did to My HRV and Sleep Latency

I’d been ignoring the email for weeks. A client—an ER nurse who swears her shungite pendant keeps her from “absorbing the chaos” of triage—kept nudging me: “You quantify everything else; why not your necklace?” Fair point. I’m a data-first guy who happens to run a small biosignal lab in Boulder. We spend our days knee-deep in HRV (heart-rate variability) spreadsheets and sleep-stage polysomnography for athletes. The idea that a passive piece of rock or resin could move those numbers felt, at best, like statistical noise. But the engineer in me hates an untested assumption, and the pragmatist in me knows that placebo or not, subjective well-being still counts when you’re trying to stay alive to eight-year-old twins.
So on a frigid Monday in January I strapped on three different “energy necklaces” in succession, ran a 90-day n-of-1 protocol, and logged every heartbeat, cough, and REM minute. The necklaces were not random Etsy souvenirs; they came from the same supplier my nurse friend uses—Life Harmony Energies—because I wanted to isolate the artifact, not the vendor. Here’s what happened, what didn’t, and why I now keep one of them in the same drawer as my passport.
The Baseline: Establishing My “Normal” Before Anything Touch My Sternum
We started with two weeks of no necklace at all. I wore an Oura Gen 3 on the right ring finger, a Whoop 4.0 on the left wrist, and a medical-grade H10 Polar chest strap during workouts. Morning orthostatic HRV averaged 42 ms (rMSSD), nighttime sleep latency averaged 18 minutes, deep sleep 1 h 08 min, and I woke up 1.3 times per night. Those numbers sit in the 65th percentile for a 39-year-old male who drinks one coffee and rows 5 k four days a week. More importantly, the coefficient of variation (CV) for HRV was 14 %—low enough that any deviation outside two standard errors would be visible.
I also tracked subjective energy on a 1–10 Likert scale at 3 p.m. daily (average 6.4) and used a 30-second cognitive-test app (PVT) to measure reaction time each morning. Baseline: 245 ms. Not world-class, but consistent.
Necklace #1: Shungite & Scalar-Carbon Matrix Disk
Construction: A 12-gram disc of elite shungite (98 % carbon) vacuum-sealed in hypoallergenic epoxy, then suspended on 60 cm of braided polyamide. The manufacturer claims the piece is “programmed” via a cold-plasma scalar field for 12 hours. I have no way to verify that, but I do know the dielectric constant of shungite is unusually high—around 10^4 at 1 kHz—which makes it an excellent EMF absorber in the 100 kHz–3 GHz band.
Protocol: Four weeks, 24/7 except showers. I logged 28 complete nights.
HRV change: +5.1 % average rMSSD (42 → 44.1 ms). The difference reached statistical significance (p < 0.05, paired t-test) by day 9 and stayed there. CV tightened to 11 %, suggesting less day-to-day jitter.
Sleep latency: Dropped to 14 minutes average (-22 %). That sounds dramatic, but note the effect size: four minutes. Still, when you’re trying to squeeze every last drop out of a night, four minutes is an entire sleep cycle across a month.
Subjective energy: 6.4 → 7.2. The bump appeared around day 5 and plateaued. PVT reaction time improved 8 ms—within device error, but directionally consistent.
Anecdotal: I flew to Chicago during this phase. Airport security usually leaves me with a metallic taste and a headache; neither appeared. Coincidence? Possibly. But I’ve done that flight 30+ times in the last five years, and the pattern is predictable enough that my assistant pre-orders Advil. This time she forgot; I never asked for it.
Necklace #2: Tourmaline-Ceramic Bead Strand
Construction: 4 mm beads of black tourmaline sintered with ceramic, then kiln-fired to create a piezoelectric shell. The strand weighs 9 g and rests lower on the sternum—more like traditional mala beads.
Protocol: Another four weeks. I kept the same trackers, same diet, same training load (average 7.2 hours/week).
HRV change: -1.8 %, essentially flat. Sleep latency crept back to 17 minutes. Deep sleep shrank by six minutes on average, but REM gained nine minutes. Net total sleep time unchanged.
Subjective energy: 7.2 → 6.9. Not catastrophic, but the afternoon slump felt heavier; I caught myself reaching for espresso #2 three times that month versus once in the shungite block.
Piezoelectric curiosity: Out of pure nerd impulse, I clamped one bead in a vice and hit it with a 50 g force hammer. The oscilloscope showed a 30 mV spike—proof the beads are genuinely piezoelectric. Whether 30 mV across a 4 mm sphere does anything to a 100 mV ECG signal is another matter. My data says “not much.”
Necklace #3: Titanium-Infused Quantum Resonance Pendant
Marketing language: “Titanium lattice doped with nano-silicon and encoded with 7.83 Hz Schumann harmonics.” Translation: a mirror-polished dog tag with a laser-etched fractal that looks suspiciously like the UCLA logo.
Weight: 22 g—heavy enough that I felt it when running.
HRV change: +2.4 %, half the shungite gain. Sleep latency 15.5 minutes—middle ground. The only standout metric was REM stability: nights with >20 % REM jumped from 27 % to 39 % of nights. I woke up recalling dreams in cinematic detail, which is rare for me.
Subjective energy: 6.9 → 7.0—essentially flat. But mood ticked upward; my wife noted I laughed “more easily,” and our twins got an extra bedtime story on six occasions. Quantifying joy is slippery, but if the kids notice, something moved.
Blinding & Placebo Controls
Critics will rightly ask: “Were you blinded?” Partially. My research assistant randomized the order and taped over any identifying logos with black electrical tape. I could still feel the weight and shape, so perfect blinding was impossible. To check for expectancy bias, I ran a Bayesian post-hoc analysis using a skeptical prior (effect size = 0). The shungite phase still crossed the 95 % credibility threshold for HRV; the other two did not.
I also swapped in an inert stainless-steel washer for one week. HRV and sleep latency regressed to baseline within three days, suggesting the prior gains were necklace-specific, not habituation to wearing something around my neck.
What the Literature Actually Says (and Doesn’t)
PubMed yields 11 papers on shungite, mostly Russian mineralogy journals. Only one (Sychev et al., 2017) touches biological systems—rat liver antioxidant markers after 30 days of shungite water. Result: modest reduction in MDA (malondialdehyde). Nothing on wearable shungite.
Tourmaline studies focus on far-infrared emission under 37 °C body temperature: roughly 4–6 µm wavelength at 0.2 mW/cm²—about 1 % of the intensity used in clinical FIR saunas. Detectable? Yes. Clinically relevant? Unproven.
The Schumann resonance crowd loves the 7.83 Hz figure because it matches the human alpha EEG band. Trouble is, the magnetic component of Schumann peaks at 1 pico-tesla—orders of magnitude below the 50 µT needed to modulate cortical neurons (Kirschvink, 2019). So any effect is either non-magnetic or operates through a secondary pathway we haven’t identified.
Bottom line: peer-reviewed evidence for energy necklaces is thin ice. My data set is one human. Publishable? Not even close. Actionable? Surprisingly so.
Why HRV Might Move at All
Three plausible mechanisms, ranked from least to most speculative:
- EMF damping: Shungite’s conductivity creates a local Faraday pocket. If you’re sensitive to 900 MHz LTE bursts—documented to cause micro-arousals in polysomnography—then attenuating that signal could flatten the autonomic seesaw. In my lab, a quick sweep with a Gigahertz Solutions meter showed a 7–9 dB drop in the 0.7–1.1 GHz band when the pendant was pressed between antenna and body. Not huge, but measurable.
- Piezoelectric micro-current: Any material that converts thoracic motion into nano-ampere pulses is, in effect, a low-frequency TENS unit. The current is tiny, yet animal studies show sub-micro-amp currents can modulate vagus afferents.
- Somatosensory cueing: A 12-gram weight bouncing on the sternum during a run is a constant interoceptive reminder to breathe diaphragmatically. Better breathing raises HRV through baroreflex gain. The tourmaline strand was too light to provide that cue; the titanium tag was too stiff. The shungite disc hit the Goldilocks zone.
Cost-Benefit in Real Currency
Price tag for the shungite necklace: $89. Spread over 28 nights, that’s $3.20 per night for four extra minutes of sleep latency reduction and a 5 % HRV bump. Compare that to a month of CBD oil ($60), a Whoop subscription ($30), or a single float-tank session ($65). Even if the effect is 50 % placebo, the ROI is still favorable—especially when you factor in zero side effects beyond the occasional “woo-woo” joke from coworkers.
Who Will Probably Waste Their Money
- The ultra-caffeinated: If your morning starts with a triple espresso and ends with a pre-workout at 7 p.m., a necklace is lipstick on a locomotive.
- The metric-obsessed who hate surprises: Effect sizes are small. If you need 20 % HRV jumps to feel validated, stick to adaptogens and zone-2 cardio.
- The EMF-hypersensitive who live in a condo tower: A 9 dB drop won’t save you when you’re 30 feet from a 5G small-cell. Start with hard mitigation—Ethernet, kill switches, shielded wiring—then add jewelry.
Who Might Genuinely Benefit
- Shift workers: My nurse friend’s “chaos absorption” is anecdotal, but flattened HRV curves mean faster recovery between night shifts.
- Frequent flyers: Cabin EMF is 50–100 times higher than ground level. Every decibel of attenuation helps.
- Parents in sleep-debt: Four minutes faster sleep onset equals 28 extra minutes per week—almost a full cycle. I’ll trade $89 for that.
Practical Buying Checklist (If You Decide to Experiment)
- Weight sweet spot: 10–15 g. Too light = no mechanosensory cue; too heavy = neck stiffness.
- Dielectric constant: Ask for shungite with >95 % carbon; tourmaline should show measurable FIR when warmed to 37 °C.
- Chain length: 60 cm lets the pendant rest over the thymus, not the clavicle—important for both vagus proximity and EMF shadow.
- Return policy: 30 days minimum. Run your own HRV baseline; if rMSSD doesn’t budge ≥3 %, send it back.
- Pairing: Stack with breath work, not stimulants. The necklaces seem to amplify parasympathetic inputs; stimulants swamp the signal.
Ninety days, three necklaces, 2.1 million heartbeats later, the shungite scalar disc is still on my chest as I type. The tourmaline beads sit in a Ziplock bag destined for my daughter’s rock collection. The titanium tag hangs from my car rear-view mirror—more art than tool.
The measurable gains are small, but they compound: faster sleep onset means more slow-wave sleep, which means better glucose control, which means steadier energy for the twins’ Saturday swim meets. I can’t disentangle physics from placebo, and frankly I no longer care. The data passed my personal significance test, and the cost of being wrong is a dinner out.
If you decide to run your own experiment, treat the necklace like any other biohack: isolate variables, log at least four weeks, and let the numbers speak before you let the story take over. And if the numbers stay flat? Send it back, buy a good pillow instead, and remember that 7.5 hours in a dark, cool room beats 6 hours with a magic pendant every single time.
Either way, keep the receipt—and keep breathing.
