What Is a Memorial Diamond? Ashes & Hair
What Is a Memorial Diamond? How Ashes and Hair Become a Real Diamond
A memorial diamond is a real laboratory-grown diamond created as a lasting keepsake to remember someone who has passed away. At BlueIce Gems, memorial diamonds are created using the HPHT (High Pressure High Temperature) diamond-growth method, with carbon recovered from cremation ashes or hair used as part of the process.
The finished stone is a genuine laboratory-grown diamond. What makes it a memorial diamond is the personal connection to the person being remembered and the use of carbon from ashes or hair as part of the diamond creation process.
For families considering a memorial diamond, the most important questions are usually simple:
- How are ashes or hair used?
- How much material is required?
- How is the diamond grown?
- How long does the process take?
- What sizes and shapes are available?
- What happens to unused material?
This guide explains the memorial diamond process, what to expect, and what you should ask before choosing a provider.
What Is a Memorial Diamond?
A memorial diamond is a laboratory-grown diamond created as a meaningful memorial to someone who has passed away. Depending on the selected process, carbon recovered from cremation ashes or hair can be incorporated into the diamond-growth process.
Unlike a diamond simulant such as cubic zirconia or moissanite, a laboratory-grown diamond is an actual diamond. It has the same fundamental crystal structure and chemical composition as a diamond created naturally, while its origin is different.
The word "memorial" describes the purpose of the diamond and its connection to a loved one.
The finished diamond can then be kept as a loose gemstone or transformed into a meaningful piece of memorial jewelry such as a pendant, ring, earrings, or another custom design.
For families, the significance is not simply the gemstone itself. It is the idea of turning a deeply personal memory into something tangible that can be carried and passed down for generations.
Are Memorial Diamonds Real Diamonds?
Yes. A memorial diamond created through a laboratory-grown diamond process is a real diamond.
At BlueIce Gems, memorial diamonds are created using the HPHT (High Pressure High Temperature) method. HPHT recreates the extreme pressure and temperature conditions required for diamond crystal growth in a controlled environment.
The process begins with a diamond seed and a carbon source. Under carefully controlled pressure and temperature conditions, carbon crystallizes around the diamond seed and gradually develops into a rough diamond.
The resulting rough diamond can then be cut, polished, and finished according to the selected specifications.
This is fundamentally different from creating a diamond simulant. The finished product is a laboratory-grown diamond rather than cubic zirconia, glass, or another material designed only to look like diamond.
How Are Memorial Diamonds Made?
Creating a memorial diamond involves several stages. While exact procedures can vary depending on the provider, the process generally begins with receiving the memorial material and ends with a finished, polished diamond.
1. Ashes or Hair Are Collected
The process begins with the collection of cremation ashes or hair from the person being remembered.
Because these materials are irreplaceable, careful handling and documentation are important throughout the process.
The material is received according to the provider's instructions and prepared for the next stage.
2. Carbon Is Recovered
Cremation ashes contain a mixture of mineral materials and other elements, so usable carbon must be processed and recovered before it can be used in diamond production.
Hair provides another possible source of carbon because it naturally contains organic carbon.
The recovered carbon becomes part of the material used during the diamond-growth process.
3. HPHT Diamond Growth
BlueIce Gems uses the HPHT method to grow memorial diamonds.
HPHT stands for High Pressure High Temperature. The technology recreates the extreme conditions under which natural diamonds form deep inside the Earth.
A small diamond seed is placed together with the prepared carbon source inside an HPHT growth environment. Extremely high pressure and temperature are applied under controlled conditions.
As the process continues, carbon crystallizes around the diamond seed and forms a rough laboratory-grown diamond.
The growth stage is one of the most technically important parts of creating a memorial diamond because the final size, quality, and characteristics of the stone depend on carefully controlled growth conditions.
4. Cutting and Polishing
Once the diamond-growth stage is complete, the rough diamond can be cut and polished.
The cut determines the final shape and has a major effect on how the finished diamond interacts with light.
Depending on the selected design, families can choose from traditional polished shapes or other available options.
5. Final Diamond Inspection
After cutting and polishing, the diamond is inspected for its final appearance, dimensions, finish, and overall quality.
The finished stone can then be prepared as a loose memorial diamond or used in a custom jewelry design.
6. Creating Memorial Jewelry
The finished memorial diamond can be set into a custom piece of jewelry.
Popular options include:
- Memorial diamond pendants
- Memorial diamond rings
- Memorial diamond earrings
- Custom heart-shaped memorial jewelry
- Other personalized jewelry designs

How Much Ash or Hair Is Needed for a Memorial Diamond?
The amount of material required depends on the provider and the selected memorial diamond process.
BlueIce Gems currently lists the following material requirements:
| Material | Required Amount | Preparation |
|---|---|---|
| Cremation Ashes | Approximately 400–500 grams | Carbon recovery and preparation |
| Hair | Approximately 5–10 grams | Carbon preparation |
The hair option can be especially meaningful for families who prefer not to use cremation ashes or want to preserve the majority of the ashes separately.
Before sending any material, we recommend confirming the exact quantity required for your selected memorial diamond.
Your ashes or hair are irreplaceable, so understanding the material requirements before shipping is an important part of the process.
Can a Memorial Diamond Be Made From Hair?
Yes. Hair can be used as a carbon source for creating a memorial diamond.
This option can be particularly meaningful when a family has preserved a lock of hair from a loved one or prefers to create a memorial without using cremation ashes.
BlueIce Gems currently lists approximately 5–10 grams of hair for one memorial diamond.
Hair and ashes follow different preparation processes, but both can provide a meaningful material connection to the person being remembered.
If you are considering using hair, contact our team before sending it so we can confirm the current material requirements and preparation instructions.
What Sizes Are Available for Memorial Diamonds?
Memorial diamonds can be created in different carat weights depending on the selected design and production requirements.
BlueIce Gems currently provides the following approximate size guide:
| Carat Weight | Approximate Diameter |
|---|---|
| 0.25 ct | 4.1 mm |
| 0.30 ct | 4.3 mm |
| 0.40 ct | 4.7 mm |
| 0.50 ct | 5.1 mm |
| 0.60 ct | 5.4 mm |
| 0.70 ct | 5.7 mm |
| 0.80 ct | 5.9 mm |
| 0.90 ct | 6.2 mm |
| 1.00 ct | 6.4 mm |
The actual appearance of a diamond also depends on its cut and proportions, so two diamonds with similar carat weights can have slightly different visual dimensions.
What Shapes Can a Memorial Diamond Have?
The shape of a memorial diamond can make the finished piece feel even more personal.
Available options may include:
- Round
- Heart
- Oval
- Cushion
- Emerald
- Radiant
- Other custom shapes depending on the selected design
A heart-shaped memorial diamond is particularly meaningful for families who want the finished stone to visually represent love and remembrance.
For a more traditional jewelry appearance, round, oval, cushion, emerald, and radiant shapes can provide a classic diamond look.
Explore our memorial diamond options to see the available designs and customization choices.
Can One Memorial Diamond Become Multiple Diamonds?
In some cases, the available material can be used to create multiple smaller memorial diamonds rather than one larger stone.
This can be meaningful for families who want several relatives to have their own memorial diamond.
For example, multiple smaller stones may be created so that children, siblings, or other close family members can each keep a personal memorial.
BlueIce Gems' published options include examples such as:
- Four diamonds of approximately 0.15 carat each
- Three diamonds of approximately 0.20 carat each
- Up to four family diamonds from one memorial commission
The exact number and size of stones depend on the selected service and production requirements.
Is My Loved One's Carbon Actually in the Diamond?
This is one of the most important questions to ask when choosing a memorial diamond provider.
The connection between the supplied material and the finished diamond depends on the provider's carbon-recovery, preparation, and material-handling process.
Cremation takes place at extremely high temperatures, meaning that the original organic material undergoes significant chemical changes. The usable carbon therefore needs to be recovered and prepared before it can be used during diamond growth.
At BlueIce Gems, the memorial diamond process uses recovered carbon from the supplied memorial material as part of the HPHT diamond-growth process.
Because the material is deeply personal and cannot simply be replaced, we believe families should understand exactly how their material is handled.
Before placing an order, ask:
- How is the material received and identified?
- How is carbon recovered?
- How is the material tracked during production?
- How is the recovered carbon introduced into the HPHT process?
- What happens to unused material?
- What documentation will be provided?
How Long Does a Memorial Diamond Take?
Creating a memorial diamond is a multi-stage process and generally takes months rather than days.
The process can include:
| Stage | Process |
|---|---|
| Material Collection | Ashes or hair are received and documented. |
| Carbon Preparation | Usable carbon is recovered and prepared. |
| HPHT Growth | The diamond is grown under controlled high-pressure and high-temperature conditions. |
| Cutting | The rough diamond is shaped into the selected cut. |
| Polishing | The diamond receives its final polished finish. |
| Inspection | The finished diamond is inspected before delivery or jewelry setting. |
| Jewelry Setting | The diamond can be placed into the selected custom jewelry design. |
The exact timeline depends on factors such as diamond size, selected color, growth requirements, cutting, polishing, and the final jewelry design.
Because every memorial diamond is created as an individual project, it is best to confirm the estimated production timeline before placing your order.
What Does a Memorial Diamond Cost?
There is no single price for every memorial diamond.
The final cost can depend on:
- Carat weight
- Diamond color
- Diamond shape and cut
- Diamond specifications
- Production requirements
- Custom jewelry design
- Metal selection
- Diamond setting
- Additional customization
When comparing memorial diamond providers, look beyond the advertised diamond price.
Ask whether your quotation includes:
- Material processing

Memorial Diamond vs. Other Memorial Keepsakes
A memorial diamond is one of several ways to preserve the memory of someone you love.
Different memorial products suit different families and different emotional needs.
| Memorial Option | Uses Remains? | Wearable? | Best For |
|---|---|---|---|
| Memorial Diamond | Ashes or hair | Yes | Long-term heirloom |
| Ash-Holding Jewelry | Small amount of ashes | Yes | Keeping ashes physically close |
| Fingerprint Jewelry | No | Yes | Personalized remembrance |
| Engraved Jewelry | No | Yes | Names, dates, or personal messages |
| Urn | Yes | No | Keeping remains together |
A memorial diamond may be ideal for someone who wants a wearable heirloom that can remain in the family for generations.
Ash-holding jewelry may be better suited to someone who wants to keep a physical portion of the ashes intact.
Fingerprint or engraved jewelry can provide personalization without using ashes or hair.
There is no universally correct choice. The best memorial is the one that feels meaningful to your family.
What Should You Ask a Memorial Diamond Provider?
Before sending ashes or hair, use this checklist when speaking with a provider.
- How much ash or hair is required?
- How is my material identified and tracked?
- How is carbon recovered from the supplied material?
- Is my material processed separately?
- Where does the HPHT diamond growth take place?
- How long does each stage take?
- What happens if the diamond does not reach the selected specification?
- What happens to unused ashes or hair?
- What is included in the quoted price?
- What documentation will I receive with the finished diamond?
A trustworthy provider should be willing to explain the process clearly before you send material that cannot be replaced.
Why Choose an HPHT Memorial Diamond?
The HPHT method is a well-established laboratory diamond-growth technology that recreates the combination of high pressure and high temperature required for diamond crystal growth.
For memorial diamonds, this allows prepared carbon to be incorporated into a controlled diamond-growth environment and transformed into a genuine laboratory-grown diamond.
At BlueIce Gems, we use the HPHT method for our memorial diamond production, combining the technology with personalized memorial jewelry options.
The goal is simple: create a genuine diamond that can become a meaningful physical reminder of someone who will always remain part of your story.
