Losing a pet is a deeply painful experience. Many owners seek a meaningful way to honor their memory. Eterneva offers a unique service: creating real diamonds from your companion's cremated remains. This Eterneva review gives an honest look at the process, costs, and experience. This will help you decide if it's the right memorial for you.
The short answer — Eterneva creates memorial diamonds from ashes, offering a lasting tribute to your pet. This is a significant investment, starting at $3,499 for a 0.25-carat stone and climbing to $42,000+ for larger sizes, with a typical 7–10 month wait. This review explores the pros and cons to help you decide.
What does Eterneva do?
Eterneva transforms your pet's ashes into a genuine, certified diamond. This isn't a synthetic simulant. It's a real diamond grown in a lab using carbon from your pet's ashes. This unique process creates a beautiful and enduring keepsake. The emotional value of this tangible reminder can be immense.
How does the process work?
Eterneva walks you through a six-step journey. First, a Welcome Kit arrives with instructions, return postage, and the container for the ashes. Once your kit is returned, lab technicians transfer the ashes into a graphite crucible and run carbon purification — a high-temperature, oxygen-controlled pyrolysis that separates pure carbon from the other elements in the cremains. That carbon then goes into an HPHT (high-pressure, high-temperature) press that replicates Earth's diamond-growing conditions for months. The rough stone is cut and polished in Antwerp, graded, laser-engraved with a unique ID, optionally color-treated, and finally returned to you — set in jewelry or loose.
What product options are available?
Eterneva offers eight colors: colorless, blue, light blue, yellow, green, red, pink, and black. Blue, yellow, and colorless develop naturally from trace elements during growth; red, green, pink, and black are created through post-growth treatment or added minerals. Cuts include the classic round brilliant and emerald, among others. For settings, you can work with Eterneva's partner jewelers on a ring, pendant, or bracelet — or leave the diamond unset and take it to your own jeweler.
How much does it cost?
Eterneva's pricing starts at $3,499 for a 0.25-carat diamond and scales up through published tiers: roughly $7,699 at 0.5 ct, $10,089 at 0.75 ct, $15,000 at 1.0 ct, $18,500 at 1.5 ct, $24,500 at 2.0 ct, and $42,000 at 3.0 ct. Anything 4.0 ct and above is quoted on request and can run to $75,000+. Color doesn't change the base price across most tiers, but setting the diamond in jewelry adds to the total.
For example, if you choose a 0.75-carat diamond, the base price is around $10,089. Adding a simple pendant setting might increase the total cost by $500 to $1,500, depending on the metal and design. Choosing a more elaborate ring setting with additional stones could easily add several thousand dollars.
Affirm financing is available from around $181/month at 0% APR over 6, 12, or 18 months. Eterneva
What is the timeline?
Plan on 7 to 10 months from mailing in the ashes to unboxing the finished diamond, with Living Diamonds running closer to 10 to 12 months. The bulk of that time is carbon purification (up to 2 months), diamond growth in the HPHT press (up to 3 months), and cutting and polishing in Antwerp (about 1 month), with grading, optional jewelry setting, and shipping on top. Eterneva sends monthly photo and video updates at each milestone — including a video of the ashes being transferred into the crucible and a notification when your stone officially becomes a raw diamond — so you're not left wondering during the wait.
What is the customer experience like?
Eterneva emphasizes customer experience, providing a documented journey with updates. You'll receive photos and videos as the diamond grows. This helps you feel connected to the process. A dedicated support team answers questions and addresses concerns. Many customers praise Eterneva's compassionate service and detail.
Pros
- Tangible Memorial: A physical and lasting tribute.
- Genuine Diamond: A real, certified diamond from ashes.
- Customizable Options: Wide range of colors, cuts, sizes, and settings.
- Documented Journey: Regular updates and photos.
- Compassionate Service: Dedicated customer support.
Cons
- High Cost: Starting price of $3,499 for the smallest 0.25-carat stone — and $15,000+ for a full 1-carat — will be out of reach for many pet owners.
- Long Wait: 7–10 months (and up to 12 for Living Diamonds) is a long time to be without the ashes.
- Limited Ash Use: Requires a specific amount of ashes.
- Emotional Investment: The process can be emotionally taxing.
- Irreversible Process: The process cannot be undone.
What are some lower-priced alternatives?
If Eterneva's price is too high, consider other memorial options. Cremation jewelry, like pendants holding ashes, is more affordable. Spirit Pieces offers glass art infused with ashes. Compared to a $3,500+ Eterneva diamond, cremation jewelry can start under $100, while Spirit Pieces range from a few hundred to a couple thousand dollars. See our guide to the best cremation jewelry.
Who is Eterneva best for?
Eterneva is best for owners seeking a unique, lasting memorial. They should be willing to invest money and time. It's ideal for those who value the symbolism of a diamond. They should appreciate the documented journey and options.
For example, imagine a family who recently lost their golden retriever, Buddy, after 14 years. They want a special memorial that reflects Buddy's unwavering loyalty and the joy he brought to their lives. They are willing to invest in a 1-carat yellow diamond set in a custom-designed ring, costing around $16,000 total.
However, if you're on a tight budget or prefer a simpler tribute, Eterneva might not be the right fit. If you want a tangible reminder and are prepared for the commitment, Eterneva could be perfect.
Our verdict
Eterneva offers a compelling option for a unique memorial. The cost and wait are significant. However, the result is a genuine diamond as a reminder of your pet. If you want a premium option and value a diamond, Eterneva is worth considering. Weigh the pros and cons to see if it aligns with your needs.
