In our previous article, “The Mystery of 3, 6 and 9: Tesla, Vibration and Crystal Healing,” we explored the fascinating world of numbers, vibration and resonance.
We also looked at one of the most commonly repeated ideas in the world of crystal healing:
Everything has a vibration.
It is a phrase you will hear frequently when talking about crystals.
You may have heard that Amethyst has a particular frequency, that Rose Quartz vibrates at a certain rate, or that different crystals can interact with the human energy field because of their individual frequencies.
But what does that actually mean?
Do crystals really have frequencies?
The surprising answer is:
Yes — but perhaps not in the way you have been told.
To understand why, we need to step away from some of the more mystical interpretations for a moment and look at what happens inside a crystal.
And once we do, the subject becomes even more fascinating.
Everything is moving
When we look at a crystal sitting quietly on a shelf, it appears completely still.
But at the microscopic level, it is anything but still.
The atoms within a solid are constantly undergoing movement.
The amount and nature of that movement depends upon temperature and the structure of the material.
In a crystal, those atoms are arranged in an ordered, repeating structure.
That structure means that the material can support different patterns of vibration.
These are sometimes referred to as vibrational modes.
So, in a very real physical sense, crystals can vibrate.
But there is an important question:
Which frequency are we talking about?
Frequency isn't one single number
This is where discussions about crystal frequencies can become misleading.
A crystal does not necessarily have one magical frequency that defines everything about it.
A physical crystal can have many different vibrational modes and resonant frequencies.
Those frequencies can depend upon things such as its:
- size
- shape
- orientation
- internal structure
- temperature
- physical constraints
In other words, the idea that every piece of Amethyst, every piece of Quartz or every piece of Rose Quartz simply has one fixed frequency is an enormous simplification.
And yet there is something very real behind the idea.
Resonance.
What is resonance?
Imagine pushing someone on a swing.
If you push at random intervals, you won't get very far.
But if you push at just the right time — matching the natural rhythm of the swing — the movement becomes much greater.
That is a simple example of resonance.
A system responds particularly strongly when it is driven at or near one of its natural frequencies.
We see resonance everywhere.
Musical instruments use it.
Buildings and bridges can experience it.
Electrical circuits can resonate.
Atoms and molecules have characteristic vibrational behaviour.
And crystals have resonant modes too.
This is not a spiritual concept.
It is physics.
Quartz: the remarkable crystal that really does resonate
Quartz is probably the most interesting crystal when discussing frequency because its relationship with resonance is not simply a matter of spiritual belief.
It is used in modern technology precisely because of its physical properties.
Quartz has a property known as piezoelectricity.
When mechanical pressure is applied to quartz, it can produce an electrical charge.
Conversely, applying an electrical voltage to quartz causes it to deform slightly.
This effect is reversible.
And when quartz is incorporated into an electronic circuit, these properties allow it to act as an extremely stable resonator.
The National Institute of Standards and Technology (NIST) explains that a quartz crystal inside an oscillator acts as the resonator. Electrical energy causes the crystal to expand and contract, while the resulting signal can be amplified and fed back into the crystal to sustain oscillation.
You can read more about how these precision mechanics establish frequency baselines on the official NIST Time and Frequency Division Portal.
This is not theoretical.
It is the reason quartz has become such an important part of modern timekeeping and electronics.
The quartz crystal in your watch
There is a wonderful example sitting in millions of homes around the world.
The quartz watch.
Most quartz watches use a tiny quartz crystal that vibrates at approximately 32,768 cycles per second, or 32,768 Hertz.
An electronic circuit counts those vibrations and divides them down until they produce the one-second timing signal used by the watch.
So every time a quartz watch advances by one second, it is ultimately relying upon the remarkably stable vibration of a tiny piece of quartz.
NIST describes quartz clocks as using the natural resonance of carefully cut quartz crystals as a frequency reference.
Think about that for a moment.
A crystal that grew naturally from the Earth has become part of the technology used to measure time.
There is something rather beautiful about that.
Does this mean crystals can “tune” our energy?
This is where we need to make an important distinction.
The fact that quartz has a measurable resonance frequency does not demonstrate that a piece of quartz held in your hand will tune your body's energy to that frequency.
That claim has not been established scientifically.
Likewise, knowing that quartz has piezoelectric properties does not prove that crystal healing works through the piezoelectric effect.
It would be tempting to make that connection.
But it would be a leap beyond the evidence.
And that is where the subject of crystals becomes particularly interesting.
Because there are actually two different conversations taking place.
One is about physical frequency.
The other is about energetic experience.
Physical frequency and energetic frequency
When a physicist talks about frequency, they are referring to something measurable.
Frequency describes how often a repeating event occurs.
It is normally measured in Hertz:
1 Hertz = 1 cycle per second.
So when we say that a quartz oscillator operates at 32,768 Hz, that is a measurable physical phenomenon.
When someone working with crystals says:
“This crystal has a high vibration,” they may be using the word vibration in a completely different way.
They may be describing how the crystal feels to them.
They may be referring to its traditional energetic associations.
They may be talking about its effect during meditation.
Or they may be using “frequency” as a way of describing a subtle energetic quality that they believe they perceive.
These ideas should not automatically be treated as though they are scientifically equivalent.
But neither does science require us to dismiss someone's personal experience simply because we cannot currently measure it.
It means we need to be precise about what we are claiming.
Why can a crystal feel different from another crystal?
This is one of the questions that people who work with crystals often ask.
Why does Amethyst feel different from Smokey Quartz?
Why does Rose Quartz feel different from Clear Quartz?
Why can someone hold two stones and experience them as completely different?
There are many possible explanations.
Some are physical.
Some are psychological.
Some are sensory.
And some are spiritual interpretations.
The physical characteristics of a crystal are certainly different from one mineral to another.
Colour, transparency, density, temperature, surface texture, shape and weight all influence our sensory experience.
But there is something else that matters enormously: meaning.
We don't experience objects in isolation
Imagine being handed two identical stones.
You are told that one is a rare and precious crystal with a long spiritual history.
You are told the other is an ordinary piece of glass.
You may experience them differently even if they are physically identical.
The information you have been given changes your expectations.
This doesn't mean that your experience is imaginary.
It means that our brains don't simply record the physical world like a camera.
We interpret it.
Expectation, memory, attention, association and emotion all influence how we experience things.
This becomes particularly relevant when we use crystals intentionally.
The crystal as an anchor
Perhaps one of the most useful ways to understand crystal healing is to think about the crystal as an anchor.
Suppose you choose a piece of Smokey Quartz because you want to spend some time focusing on grounding and stability.
You hold the crystal.
You sit quietly.
You breathe more slowly.
You put your phone away.
You spend ten minutes without interruption.
The crystal becomes associated with that experience.
After doing this repeatedly, simply holding the crystal may remind you of the state you were trying to cultivate.
The stone has become an anchor for attention.
Whether you describe that as energy, intention, mindfulness, conditioning or ritual depends upon the framework you prefer.
But the experience can still be meaningful.
What does the research tell us?
This is where things become particularly interesting.
A 2025 randomised controlled study examined whether healing crystals could reduce anxiety and whether any benefit was specifically associated with Rose Quartz.
The study involved 138 adults who were divided according to whether they already believed in the efficacy of healing crystals.
Participants were randomly given either Rose Quartz or a visually matched placebo crystal and followed a standardised 14-day protocol.
The researchers found reductions in anxiety among believers — but there was no significant difference between those who received Rose Quartz and those who received the placebo crystal.
The results therefore did not demonstrate a specific therapeutic effect from the crystal itself.
Instead, the researchers found results consistent with expectancy and conditioning effects.
At first glance, that might seem like an argument against crystal healing.
But there is another way of looking at it.
The fascinating power of expectation
The placebo effect is sometimes described as though it means:
“It's all in your head.”
That phrase doesn't really do it justice.
The brain is extraordinarily powerful.
Our expectations can influence how we perceive symptoms, discomfort, stress and wellbeing.
If an object becomes associated with relaxation, safety or a particular intention, using that object may help reinforce the experience.
That doesn't mean the object has magical powers.
It means that the context surrounding an experience can matter.
And this is something that anyone who has ever developed a personal relationship with a favourite crystal may recognise.
Does that make crystal healing meaningless?
I don't think it does.
But it does invite us to think more carefully about what we mean by “healing”.
A crystal should never be presented as a replacement for appropriate medical diagnosis or treatment.
Nor should we claim that a particular crystal can cure a medical condition simply because it is said to possess a certain frequency.
There is currently no good scientific evidence establishing those claims.
But crystals can still have a meaningful role in meditation, reflection, ritual and personal practice.
A stone can remind you to stop.
To breathe.
To reflect.
To focus.
To reconnect with an intention.
And sometimes, simply creating a few quiet minutes in a busy day can be valuable.
Perhaps resonance has another meaning
There is another reason I like the word resonance when talking about crystals.
We use it scientifically to describe a physical response at a particular frequency.
But we also use the word in everyday life.
We say:
“That really resonated with me.”
We don't mean that our body literally began vibrating at a measurable frequency.
We mean that something connected with us.
A song can resonate.
A memory can resonate.
A person's words can resonate.
A place can resonate.
And perhaps a crystal can resonate with us in this more personal sense too.
It can become associated with a particular period of our lives, a particular intention or a particular emotional experience.
That is a form of resonance worth exploring.
What about the famous “crystal frequencies” you see online?
You will sometimes find tables online giving precise frequencies to different crystals.
For example, a particular mineral may be assigned a frequency in Hertz and that frequency may then be associated with a chakra, organ or emotional state.
These claims should be approached carefully.
There is a fundamental difference between:
“This crystal has measurable vibrational modes.”
and:
“This crystal vibrates at a specific frequency that heals a particular part of the human body.”
The first is consistent with physics.
The second requires scientific evidence that has not been established.
It is perfectly possible to enjoy the symbolic or spiritual associations of a crystal without presenting them as established scientific facts.
In my view, that makes our relationship with crystals more interesting, not less.
So, do crystals really have a frequency?
Yes.
Crystals are physical structures capable of supporting vibrations and resonances.
Quartz is an especially remarkable example because its piezoelectric properties allow it to function as a highly stable resonator in electronic devices.
But that doesn't mean that every crystal has one single mystical frequency, or that those frequencies have been scientifically demonstrated to heal the human body.
The word frequency is often being used in two very different ways.
There is the measurable frequency of physics.
And there is the language of energetic and spiritual experience.
Understanding the difference allows us to explore both without confusing one with the other.
Perhaps the question isn't “What frequency is my crystal?”
Perhaps a more interesting question is:
“What does this crystal help me focus upon?”
That question takes us back to the heart of crystal healing.
Maybe the most valuable part of working with a crystal isn't discovering that it has a secret numerical frequency.
Maybe it is discovering what happens when we give ourselves permission to slow down and pay attention.
The crystal becomes a physical object around which we can build an experience.
An intention.
A meditation.
A ritual.
A moment of stillness.
And perhaps that is where the idea of resonance becomes most meaningful.
Not simply:
What is the frequency of the crystal?
But:
What resonates within me when I hold it?
Continuing the journey
In our previous article, we explored the mystery of 3, 6 and 9, Tesla and the fascinating relationship between numbers and vibration.
Here we have gone one step further and discovered that crystals really do have measurable vibrational and resonant properties — particularly quartz — but that this scientific reality should not be confused with claims that specific crystal frequencies have been proven to heal particular conditions.
There is still plenty to explore.
Because if crystals can resonate physically, and if human beings can experience resonance emotionally and psychologically, another fascinating question naturally follows:
Could resonance itself help explain why crystals have played such a powerful role in meditation, ritual and spiritual practice for so many people?
Perhaps that is where our next journey begins.
