If you have started researching what to do with a loved one's cremated remains, you have probably come across Eterneva -- a company that turns ashes (or hair) into a lab-grown memorial diamond. The concept is striking, deeply personal, and, understandably, prompts a lot of questions about how it works and what it costs.
This guide is a balanced, factual review of Eterneva as of 2026. We cover what the company is, how the diamond-creation process works, what is included, the typical price ranges you can expect, the genuine pros and cons, who the service is best suited for, and more affordable alternatives. Because memorial-diamond pricing is highly customized and not always fully public, we frame all costs as typical ranges to confirm at quote time -- never as guaranteed figures.
What Is Eterneva?
Eterneva is an Austin, Texas-based company that creates lab-grown memorial diamonds from the carbon contained in cremated remains or in a lock of hair. The idea is that a small amount of ash or hair is processed to extract carbon, and that carbon is then used in a high-pressure, high-temperature (HPHT) process to grow a real diamond over a period of months.
The result is a genuine, certified lab-grown diamond -- chemically and physically identical to a mined diamond -- that a family can keep, set into jewelry, or pass down. Eterneva markets the experience as a celebration of a life rather than simply a product, and the company is known for a high-touch, communicative process that keeps families updated at each stage.
It is worth being clear about what Eterneva is not. It is not a cremation provider, a funeral home, or a crematory. You arrange the cremation itself through a local cremation provider or funeral home, and Eterneva works with the ashes afterward. If you have not yet arranged cremation, start with our guide on what is direct cremation.
How the Eterneva Process Works
Eterneva's process is built around the science of growing a diamond from carbon. While the exact steps and timelines can change, the general journey looks like this:
- Welcome kit and collection. After ordering, you receive a kit to send in a small amount of ashes (commonly around half a cup) or a lock of hair. Only a small portion of remains is needed, so families can keep the rest.
- Carbon extraction and purification. The lab isolates and purifies the carbon from the sample. This step is one reason hair is sometimes used as a backup, since carbon content can vary.
- Diamond growth (HPHT). The purified carbon is placed in a chamber that recreates the intense heat and pressure found deep in the earth. The diamond grows over a period that typically spans several months.
- Cutting, grading, and certification. The rough diamond is cut to the chosen shape and graded. Eterneva provides documentation of the diamond's characteristics.
- Return and optional setting. The finished diamond is returned to the family, often in a presentation ceremony, and can be set into a ring, pendant, or other jewelry.
Start to finish, the experience commonly takes several months -- often in the range of 7 to 10 months depending on the diamond size and options. Eterneva emphasizes regular communication throughout, which many families find meaningful during grief.
What Is Included
A memorial diamond order generally includes more than just the stone. Based on how the service is typically structured as of 2026, you can usually expect:
- The diamond-creation process itself, from carbon extraction through growth
- A welcome/collection kit for safely sending ashes or hair
- Status updates and communication throughout the months-long process
- Certification or documentation describing the finished diamond
- Return shipping of the diamond, often with a presentation experience
- Optional add-ons such as jewelry settings, additional diamonds, color choices, and faster timelines (these increase the price)
Always confirm exactly what a given package includes before ordering, since inclusions and add-on pricing change over time.
Eterneva Cost: Typical 2026 Price Ranges
Here is the honest reality: memorial diamond pricing is highly variable, depends heavily on carat size, color, and cut, and is not always published in full. Treat the figures below as widely-reported typical ranges as of 2026, to be confirmed in a written quote -- not as fixed prices.
| Factor | What it means | Typical effect on price |
|---|---|---|
| Carat size | Smaller stones cost less; larger ones cost much more | The single biggest driver |
| Color | Colorless, yellow, blue, and other options | Some colors cost more |
| Cut/shape | Round, princess, and other cuts | Varies by complexity |
| Setting/jewelry | Ring, pendant, or loose stone | Optional add-on cost |
| Timeline | Standard vs. expedited | Faster can cost more |
As a general guide, smaller memorial diamonds commonly start in the low-to-mid four figures (roughly $3,000), mid-size stones often land in the mid four to low five figures, and larger or premium-color diamonds can run into the tens of thousands of dollars ($50,000 or more). Many providers in this category offer payment plans that spread the cost over several months.
Crucially, this cost is on top of the cremation itself. A standard direct cremation typically runs $1,000 to $3,000 in most US metros, so the memorial diamond is an additional, separate expense. To understand baseline cremation pricing in your area, see our average cremation cost by state for 2026.
Because of how much customization affects the final number, the only way to know your real cost is to request a written, itemized quote directly from Eterneva for the exact specifications you want.
Pros of Eterneva
- A lasting, wearable memorial. A diamond is durable and can be kept close, set into jewelry, and passed down through generations.
- Only a small amount of ashes is used. Families can still scatter, bury, or keep the remaining remains.
- Real, certified diamonds. The output is a genuine lab-grown diamond with documentation, not an imitation stone.
- High-touch experience. Eterneva is known for frequent communication and a personal, ceremony-style return, which some families find comforting.
- Hair is an option. Diamonds can be made from hair, which opens the service to families who did not choose cremation or who want a memorial from a living person or pet.
Cons of Eterneva
- Cost. This is a premium memorial option. Prices far exceed simpler keepsakes, and the total is in addition to cremation costs.
- Long timeline. Waiting several months for the finished diamond may not suit families who want a memorial quickly.
- Pricing is not fully transparent up front. Because cost depends on customization, you often need to request a quote rather than see a simple price list.
- It is an emotional and financial commitment. Sending a loved one's ashes away for months is a significant decision, and the expense can be hard to justify on a tight budget.
Who Eterneva Is Best For
Eterneva tends to be a good fit for families who:
- Want a single, lasting, wearable keepsake rather than (or in addition to) an urn
- Can comfortably afford a premium memorial as a separate expense from cremation
- Value a guided, communicative experience over a fast, transactional one
- Like the idea of a tangible heirloom that can be passed down
It is likely not the best fit for families on a tight budget, those who need a memorial quickly, or those who would prefer to direct funds toward the cremation and a simpler remembrance. If budget is a primary concern, see our guide on affordable cremation options and how to save.
More Affordable Alternatives to a Memorial Diamond
A memorial diamond is one of the higher-cost ways to memorialize a loved one. If you love the idea of keeping ashes close but want a lower price point, consider these alternatives:
- Cremation jewelry. Pendants, rings, and bracelets that hold a tiny amount of ashes typically cost from the low tens to a few hundred dollars. See our cremation jewelry guide.
- Keepsake urns and dividing remains. Small keepsake urns let multiple family members each keep a portion of the ashes.
- Other ash-based memorials. Glass art, pressed stones, and similar items generally cost far less than a diamond while still incorporating the remains.
For a broader look at memorial options, our overview of cremation ashes keepsakes and memorials walks through the full range, and what to do with cremation ashes covers scattering, burial, and other choices.
Whatever memorial you choose, the cremation itself comes first. Local pricing varies widely, so it is worth comparing providers in your area before you commit. Families in cities like Austin, Columbus, Nashville, San Diego, Atlanta, and Portland can use our directory to request itemized quotes and compare direct cremation costs locally.
How to Get an Accurate Eterneva Quote
Because pricing depends so heavily on specifications, follow these steps to get a realistic number:
- Decide on size, color, and cut. These are the main cost drivers, so settle them before requesting a quote.
- Ask what is included. Confirm whether the price covers certification, return shipping, and any presentation experience -- and what jewelry settings cost.
- Get it in writing. Request a written, itemized quote so you can compare it against alternatives and avoid surprises.
- Ask about timeline and payment plans. Confirm the expected delivery window and whether installment options are available.
- Compare against simpler memorials. Weigh the diamond against cremation jewelry or keepsake options to be sure it fits your budget and wishes.

Frequently Asked Questions
How much does an Eterneva diamond cost in 2026?
As of 2026, memorial diamonds from companies like Eterneva typically start in the low-to-mid four figures (around $3,000) for smaller stones and can rise into the tens of thousands of dollars ($50,000 or more) for larger or premium-color diamonds. The exact price depends on carat size, color, and cut, and is separate from the cost of cremation. Always request a written quote for your specific choices.
Is the cost of cremation included in an Eterneva diamond?
No. Eterneva creates a diamond from ashes you already have, so the cremation itself is a separate expense arranged through a funeral home or cremation provider. A standard direct cremation typically runs $1,000 to $3,000 in most US metros, in addition to the diamond's cost. See our average cremation cost by state guide for local figures.
How long does it take to turn ashes into a diamond?
The process commonly takes several months -- often in the range of 7 to 10 months -- depending on the diamond's size and the options you select. Larger diamonds and certain colors can take longer. Eterneva typically provides updates throughout the growth process so families can follow along.
How much ash is needed for a memorial diamond?
Only a small amount of cremated remains is required -- commonly around half a cup -- which means families can keep, scatter, or bury the rest. If carbon levels in the ashes are insufficient, a lock of hair can be used as an alternative source of carbon. Confirm the current requirements with the provider before sending anything.
Are there cheaper alternatives to a memorial diamond?
Yes. Cremation jewelry that holds a small amount of ashes typically costs from the low tens to a few hundred dollars, and keepsake urns let multiple family members each keep a portion of the remains. Glass art and other ash-based memorials are also far less expensive. See our cremation jewelry guide and cremation ashes keepsakes and memorials for lower-cost options.
Is an Eterneva memorial diamond a real diamond?
Yes. The result is a genuine lab-grown diamond, chemically and physically identical to a mined diamond, created from the carbon in cremated remains or hair using a high-pressure, high-temperature process. Eterneva provides documentation describing the finished diamond's characteristics.
