Mother Ashes and Hair Diamond: The Complete Guide
Most families arrive at this holding two different things and assuming they have to pick one. You don’t.
A mother ashes and hair diamond is a genuine lab-grown diamond created using carbon extracted from both her cremated remains and a lock of her hair. The two materials are purified separately and then prepared for the diamond-growth process.
Hair contains roughly 50% carbon by weight, while cremated ashes contain a much smaller amount of usable carbon. Combining both materials can therefore increase the amount of personal carbon recovered from the submission.
There is also another option that many families may not realize they have: instead of creating one blended stone, it may be possible to create two separate diamonds one associated with ashes and one associated with hair.

Why Would You Submit Both Her Ashes and Her Hair?
The two materials can carry different meanings.
Ashes are what many families associate with a loved one’s physical remains. They are what is returned after cremation and what families often preserve, scatter, or keep in an urn.
Hair is different. A lock of hair can remain deeply personal because it is visibly connected to the person you remember. From a technical perspective, hair also contains a relatively high proportion of carbon.
Hair is roughly half carbon by weight, while cremated remains are primarily mineral material, with usable carbon generally representing a much smaller proportion.
For some families, submitting both materials simply feels meaningful. It allows both the cremated remains and a physical lock of hair to be represented in the process.
You do not necessarily have to choose between them.
If you are still deciding which material is right for your situation, you may also want to explore an ashes-only memorial diamond, a hair-only memorial diamond, or compare ashes and hair as starting materials.
What Does Combining Ashes and Hair Actually Change About the Diamond?

The most important change is the amount of personal carbon that may be recovered from the submitted materials.
Hair contains considerably more carbon by weight than cremated ashes. Adding hair to an ashes submission can therefore increase the total amount of carbon recovered from the person being memorialized.
| Source Material | Approximate Carbon Content | What It Contributes |
|---|---|---|
| Cremated Ashes | Approximately 0.5–4% | A smaller amount of usable personal carbon among mineral-rich material |
| Hair | Approximately 50% | A relatively carbon-rich source |
| Ashes and Hair Combined | Higher total personal carbon than ashes alone | Carbon from both submitted materials can contribute to the growth feedstock |
However, combining ashes and hair does not mean that the finished diamond is made entirely or exclusively from the submitted material.
Diamond growth requires a sufficient amount of carbon feedstock. Personal carbon recovered from ashes, hair, or both may be combined with supplemental laboratory carbon during the growth process.
The most accurate way to understand a combined memorial diamond is that carbon recovered from both her ashes and her hair contributes to the material used to create the stone.
Should You Grow One Blended Stone or Two Separate Diamonds?
Having both ashes and hair creates a decision that families using only one material do not have.
You may consider creating one memorial diamond using both materials, or creating two separate diamonds associated with the two different source materials.

Why Some Families Choose Two Diamonds
- Two family members can each have a stone. One diamond can represent the ashes and another can represent the hair.
- One to wear and one to keep. A family may choose to set one diamond into jewelry while preserving another stone separately.
- Different meanings for different pieces. One stone may be intended as a formal family heirloom while another feels more personal.
- Separate keepsakes. Two diamonds can provide more flexibility for sharing a memorial between family members.
Why Some Families Choose One Diamond
One stone can also feel simpler.
There is one diamond size, one shape, one color, one setting, and one finished piece to preserve or pass down.
Creating two separate diamonds may also involve two separate production processes, cutting stages, and grading requirements.
The right choice depends less on chemistry and more on what makes sense for your family.
What If You Only Have a Very Small Amount of One of Them?
This is a common situation.
A Little Hair and Plenty of Ashes
You may only have a few strands from a brush, comb, keepsake, or baby book.
Because hair contains a relatively high percentage of carbon by weight, even a small amount may still contribute carbon alongside the ashes. Always tell the provider exactly how much material you have before cutting or sending it.
A Little Ash and Plenty of Hair
Perhaps most of the ashes were scattered or interred years ago, but a small portion was kept.
A combined submission may still be worth discussing with a memorial diamond provider because both materials can be evaluated individually.
Almost None of One Material
If you have only a tiny amount of one material, ask the provider honestly what practical role it can play in the process.
Even when the contribution is primarily symbolic, that may still be meaningful to the family. The important thing is understanding the difference between a symbolic contribution and a significant material contribution.
How Does a Laboratory Handle Two Different Materials?

Ashes and hair are very different materials, so they require different purification processes.
They are handled separately during the early stages.
Step 1: Processing the Ashes
Cremated remains contain substantial mineral material, including calcium phosphate and other components associated with bone.
The laboratory processes the material under controlled conditions to isolate usable carbon.
Step 2: Processing the Hair
Hair is primarily composed of keratin and contains a relatively high amount of carbon.
The hair is processed separately to remove non-carbon components and other possible residues.
Step 3: Carbon Purification
The goal of both processes is highly purified carbon suitable for later preparation and diamond growth.
The purified material is then prepared for the next stage of the process.
Step 4: Graphitization
The carbon can be converted into graphite at extremely high temperatures, approximately 2,500–2,700°C.
Step 5: Diamond Growth
The prepared carbon feedstock is placed into a diamond-growth environment together with a small diamond seed.
In an HPHT, or High Pressure High Temperature, process, the environment may reach approximately:
- 6–8 GPa of pressure
- 1,400–2,500°C of temperature
Under these controlled conditions, carbon atoms gradually attach to the diamond seed and form a growing crystal.
The growth process can take weeks to months depending on the target diamond.
Step 6: Cutting and Polishing
The diamond crystal that comes out of the growth process is a rough diamond.
A specialist examines the crystal and determines how it can best be cut and polished.
The finished diamond can then be evaluated according to characteristics such as:
- Cut
- Color
- Clarity
- Carat Weight
Does Sending More Material Create a Bigger Diamond?
No. Sending more ashes or more hair does not automatically create a larger diamond.
The final carat weight depends primarily on the selected diamond size and the controlled crystal-growth process.
Growth time and laboratory conditions play a much larger role in determining the size of the finished stone than simply increasing the amount of submitted material.
Does Submitting Both Change the Timeline or Cost?
For one combined memorial diamond, submitting two types of material may not dramatically change the overall timeline.
The complete process can take several months because diamond crystal growth, cutting, polishing, and certification require time.
A typical industry timeline can be approximately 6 to 10 months, with larger diamonds or specialized requirements potentially taking longer.
If you choose to create two separate diamonds, each stone may follow its own production timeline.
What Determines the Cost?
The cost of a memorial diamond is generally influenced more by the characteristics of the finished diamond than by simply submitting one or two source materials.
Factors may include:
- Carat weight
- Diamond color
- Cut and shape
- Clarity characteristics
- Certification or grading
- Whether one diamond or multiple diamonds are created
If two separate diamonds are produced, expect the production requirements to be more comparable to creating two individual stones rather than one.

One Mother’s Story Can Become One Stone or Two
If you have both your mother’s ashes and a lock of her hair, you have more options than you may initially realize.
You may choose one memorial diamond representing both materials. Or, depending on what is available and what your family wants, you may consider separate stones.
There is no universally better choice.
For some families, one stone feels complete. For others, two diamonds make sharing, wearing, or preserving the memorial easier.
The best first step is understanding what materials you have and discussing the possibilities before sending anything irreplaceable.
Frequently Asked Questions About Mother Ashes and Hair Diamonds
Does adding hair make the diamond more genuinely her than ashes alone?
Adding hair can increase the amount of personal carbon recovered from the submitted materials because hair contains significantly more carbon by weight than cremated ashes. However, supplemental laboratory carbon may still be required during diamond growth.
Can we grow one diamond from her ashes and another from her hair?
Creating separate memorial diamonds associated with different source materials may be possible. Discuss the available options with the provider before sending either material.
Are the ashes and hair mixed together from the beginning?
No. Ashes and hair have very different compositions and require different purification processes. The materials can be processed separately before being prepared for diamond growth.
Does submitting both materials cost more?
For one combined stone, cost is generally influenced primarily by the characteristics of the finished diamond. Creating two separate diamonds requires separate production processes and may cost closer to producing two individual stones.
What if we only have a few strands of her hair?
A small amount of hair may still be useful because hair contains a relatively high percentage of carbon. Tell the provider exactly how much you have before cutting or sending it.
Will a combined diamond look different from an ashes-only or hair-only diamond?
Not necessarily. The appearance of a diamond is primarily influenced by the conditions used during growth, as well as factors such as trace elements, cutting, and polishing.
Does more hair or more ashes create a larger diamond?
No. Diamond size depends primarily on the selected carat weight and the controlled crystal-growth process, not simply on the quantity of material submitted.
How long does it take to create a memorial diamond?
The complete process can take several months. Industry timelines are commonly around 6 to 10 months, depending on the desired diamond size, growth process, cutting, and certification.
Is a memorial diamond a real diamond?
A properly grown memorial diamond is a laboratory-grown diamond crystal. Like other lab-grown diamonds, it can be evaluated according to characteristics including cut, color, clarity, and carat weight.
Where to Start
If you have both your mother’s ashes and a lock of her hair, start by understanding how much of each material you have.
Then consider what feels right for your family: one diamond representing both materials, or separate memorial diamonds.
Before sending anything irreplaceable, ask about material requirements, handling procedures, chain of custody, expected timeline, available diamond sizes, and the documentation provided with the finished stone.
A conversation is often a better first step than making an immediate purchase decision.
