My resting heart rate is 58 BPM. Every weekday at 9:47 AM, thirty seconds before my webcam turns on for standup, it reads somewhere between 115 and 131. My smartwatch genuinely thought I was exercising.
I have been a backend developer for eleven years. I can explain event loops to interns without blinking, but put me in a circle of nine faces on Zoom and my chest gets tight around minute two, right before it is my turn. In May I fumbled a demo to our VP so badly that my manager asked me privately if everything was okay at home. Everything was fine at home. I just hate being watched while I talk.
Somewhere in that post-demo shame spiral I ended up reading about the solar plexus chakra — Manipura, the so-called city of jewels, allegedly the energy center that handles confidence and personal power. Citrine, tiger's eye, pyrite, sunstone. The usual prescription for people who feel small in meetings.
Look. I don't believe rocks emit confidence. But I do believe in experiments, spreadsheets, and my smartwatch, so I turned it into one.
The setup
I bought five stones from an actual crystal shop on June 1st. Total damage: $87.
- Citrine bracelet — $29
- Tiger's eye palm stone — $18
- Raw pyrite chunk — $14
- Sunstone tumbled stone — $11
- Rutilated quartz pendant — $15
Why a shop and not Amazon? Because I tried the Amazon route first and almost everything labeled citrine is heat-treated amethyst — that unnatural saturated orange. Real citrine is pale, almost smoky yellow. The shop owner pulled out both versions and let me compare side by side. That kind of honesty is worth something.
The protocol was simple:
- June 2–15: baseline. No stones. Just data.
- June 16 – Aug 31: each stone got exactly two weeks, in the order above.
- Every weekday at 9:45 AM, seated, I recorded my heart rate from the watch.
- After standup I logged a confidence self-rating (1–10) and one binary: did I speak up without being asked?
One week off in July for vacation (no standups, no stones, no data). Everything else was normal coffee, normal sleep, normal morning dread.
The numbers
Sixty standups logged. Here is the entire dataset:
| Stone | Avg HR before standup | Avg confidence /10 | Spoke up (days of 10) |
|---|---|---|---|
| None (baseline) | 119 | 4.1 | 5 |
| Citrine bracelet | 107 | 5.8 | 7 |
| Tiger's eye | 102 | 6.4 | 8 |
| Pyrite | 115 | 5.0 | 6 |
| Sunstone | 110 | 5.5 | 6 |
| Rutilated quartz | 116 | 4.9 | 5 |
Two things jumped out. Tiger's eye was the clear winner — average heart rate dropped 17 BPM from baseline, and I spoke up on 8 out of 10 days, which for me is unheard of. Pyrite and rutilated quartz did roughly nothing, which is interesting because pyrite is supposedly the confidence stone if you read Etsy listings.
I should also be honest about the messiest data point: August 20, the sprint demo in front of the VP. Tiger's eye in my left hand, and my heart rate hit 131 anyway. The stone did not delete the anxiety. Nothing deletes the VP.
What I actually think happened
Here is my honest take after 90 days: the stone probably matters less than the ritual. But the ritual matters more than I expected.
Holding the stone for two minutes before standup forced me to stop tab-switching and breathe. Three rounds of 4-7-8 breathing, stone in hand, then join the call. Slower exhales downregulate your nervous system — that is just physiology. The stone is the anchor that makes me actually do it, instead of telling myself I will breathe later. I never breathe later.
So is it placebo? Maybe. If it is, it is an $18 placebo that got me to voluntarily demo our new API in front of thirty people at the August meetup, something I had dodged for three years. I will take that trade.
When the VP demo spiked my numbers anyway, I started reading about the panic flavor of anxiety versus the performance flavor, and apparently that is where root chakra stones come in — grounding work instead of confidence work. My next experiment, probably October, is testing that during on-call weeks. The one after that might be third eye chakra stones for deep-work focus, tracked with RescueTime instead of a heart rate monitor. My watch is going to need a vacation.
If you want to try this
Things I would tell a skeptic friend, in order:
- Spend max $25 on a first stone. Tiger's eye and citrine are the cheap, hard ones that survive pockets and laptop bags.
- The ritual beats the rock. Two minutes, stone in hand, three rounds of 4-7-8 breathing. The stone just makes the ritual real.
- Track one objective number for two weeks before you judge anything. Heart rate, did-I-speak-up, whatever. Vibes are not data.
- Buy from a real shop. Heat-treated amethyst sold as citrine is the exact same dynamic as a genuine leather belt for six dollars.
- Calibrate expectations. A stone got me from 119 to 102 BPM before standups. It did not save the VP demo. Nothing saves the VP demo.
If you are curious about the framework I was stealing from, SagStone's solar plexus guide is where I started — it maps stones to the confidence work without the incense-shop energy. Their beginner's guide to crystal healing is the least woo-adjacent resource I found when I was figuring out what I was even doing. The rest of their blog covers the other chakras, in case standups are not your particular demon.
Ninety days ago I would have told you crystals are a scam. Now I would tell you something more annoying: I don't know exactly why it works, but my average standup heart rate is 17 BPM lower and I raised my hand 60% more often. My smartwatch and my spreadsheet both say something changed. The physicist in me says placebo. The guy who dreads 9:47 AM says he doesn't care what it's called.
