Eterneva Review
The most transparent memorial diamond company in the US, and the one fact that matters most is one they publish themselves: your pet's own carbon makes up 10 to 15 percent of the finished stone. Prices run $3,499 to $75,000 and the wait is 7 to 10 months. If you know that going in, the experience they build around it is genuinely exceptional.
Eterneva turns cremated ashes, hair or fur into a laboratory-grown diamond. The company is based in Kerrville, Texas, grows its diamonds in its own US lab, and says nearly half of the diamonds it makes are for pets. It publishes a full price table by carat and color, which almost nobody else in this category does, and it publishes the composition of the finished stone, which nobody else in this category does at all.

What They Do Well
They tell you what is actually in the diamond. On their own science page, Eterneva states that the personal carbon extracted from your pet makes up 10 to 15 percent of the carbon used to grow the stone, blended with generic carbon because the trace impurities in cremated remains would otherwise compromise clarity and growth. This is true of every memorial diamond company. Eterneva is the one that writes it down. We looked hard for a competitor doing the same and did not find one. A family spending several thousand dollars deserves to know that, and the company that volunteers it before you ask is telling you something about how it operates.
The price table is fully published. Carat by carat, color by color, on a public page, with no form to fill in. Black, red, yellow, blue, green, colorless, pink and light blue all cost the same at a given size, so choosing your pet's color is a free decision rather than an upsell. In a category built on emotional pricing, a public grid is worth a lot.
Only half a cup of ashes is needed. This is the fear that stops most people from enquiring: that making a diamond means giving up your pet entirely. It does not. Half a cup of ashes, or a cup of fur, is enough, and Eterneva will store the unused carbon for life at no charge. The rest of your pet stays with you, in an urn or wherever you choose.
The waiting is designed, not endured. You get a digital tracker with photographs and video at each stage, a named care team, and an open invitation to tour the Texas lab or hand-deliver the ashes yourself. Over a 7 to 10 month process, that is not a marketing flourish. It is the difference between a long silence and something to follow.
Independent recognition that is not self-awarded. A BBB Ethics Award, and first place for Most Personalized Pet Memorial from the International Cemetery, Cremation and Funeral Association. Third-party carbon testing of your ashes is available on request. Free engraving on the girdle of the stone is included.
Where They Fall Short
The price per carat rises much faster than the carat. A 0.25 carat stone is $3,499. Half a carat, twice the size, is $7,699, more than double. One carat is $15,000, over four times the price for four times the size. Three carats is $42,000. There is nothing improper about this, larger stones are genuinely harder to grow, but families often anchor on the $3,499 starting figure and then discover that the size they pictured costs five times that. Decide your budget before you look at the size chart, not after.
A comparable lab-grown diamond from an ordinary jeweller costs a fraction of this. You are not paying for the gemstone, you are paying for the provenance, the process and the year of care around it. That can be entirely worth it. But be clear with yourself that this is what you are buying, because a jeweller will sell you a one carat lab-grown diamond for a small share of $15,000 and it will look the same.
Seven to ten months is a long time. Grief moves. The person who orders in month one is not the same person who opens the box in month nine, and for some families that gap is the best part of the experience while for others it keeps the loss open longer than they wanted. There is no faster option.
You have to post your pet's ashes. They provide a welcome kit and return postage, and the process is clearly documented, but for some people the act of putting a portion of their pet in the mail is the barrier, and no amount of tracking removes it.
The public review base is thinner than the customer base. Eterneva cites more than 4,000 families served, while the Trustpilot profile it links to carries a comparatively small number of reviews. The reviews that exist are strong. There are just not many of them relative to the size of the business, so weigh them accordingly.
Pricing Deep Dive
Eterneva publishes a full price grid by carat. Every color costs the same at a given size, with the single exception that green is not offered at the smallest size:
- 0.25 carat: $3,499
- 0.5 carat: $7,699
- 0.75 carat: $10,089
- 1.0 carat: $15,000
- 1.5 carat: $18,500
- 2.0 carat: $24,500
- 3.0 carat: $42,000
- 4.0 carat: $60,000
- 5.0 carat: $75,000
- 4.0 carat and above: call for price
Colors available: black, red, yellow, blue, green, colorless, pink and light blue. Cuts include round, heart, emerald, radiant, asscher and cushion.
What is included at every price: the digital diamond tracker with photos and video at each milestone, a named care team, free engraving on the girdle of the stone, lifetime storage of any carbon not used, and GIA-style certification. Third-party carbon testing of your ashes is available on request.
To start you order a Welcome Kit, normally $50 and at the time of writing discounted to $1, which contains the container, instructions, return postage and cubic zirconia samples so you can see the carat sizes in your hand before committing.
The jewelry setting is priced separately from the stone.
Financing is offered, and the price grid shows monthly payments from about $292 for the smallest stone, subject to qualification.
For scale. Private pet cremation itself typically runs $220 to $325 for a medium dog on our city pages. A cremation jewelry pendant holding a small portion of ashes usually runs $50 to $300. Parting Stone, which converts all of your pet's remains into a set of smooth stones you can hold, charges $1,195 for a cat or a dog, with about a 10 to 12 week turnaround. Eterneva's entry price is roughly three times that, and its one carat price roughly twelve times. Whether that is worth it is a personal judgment, not a factual one, and we are not going to make it for you.
A strong fit if:
- Families who want one permanent object rather than a container of ashes, and for whom cost is not the deciding factor
- People who want to know exactly what they are buying, since Eterneva discloses the carbon composition that competitors do not
- Families who find a long, documented process comforting rather than prolonging
- Anyone who wants to keep most of their pet's ashes and use only a small portion
Consider alternatives if:
- Anyone who assumes the diamond is made entirely from their pet, since 10 to 15 percent of the carbon is personal and the rest is generic
- Families who need something in hand within weeks rather than most of a year
- Budgets under a few thousand dollars, where solidified remains or ash-inclusion jewelry give a physical keepsake for far less
- People who are not comfortable posting a portion of their pet's ashes
Other Options to Consider
Pulvis Art Urns: if what you want is something beautiful to hold your pet rather than a gemstone, handmade ceramic urns run roughly $89 to $600 and arrive in days rather than months. OneWorld Memorials: the broadest mainstream range of pet urns and keepsakes, from about $50, with a 30 day money back guarantee on unengraved items.
Our Verdict
Every memorial diamond is mostly generic carbon. That is not a scandal, it is chemistry: cremated remains carry too many trace impurities to grow a clean stone unaided. What separates the companies in this category is whether they tell you.
Eterneva tells you. It publishes the 10 to 15 percent figure on its own website, publishes a full price grid instead of a quote form, publishes where the lab is and invites you to walk through it. For a purchase this expensive, made at the worst possible moment for clear thinking, that pattern is the strongest thing they have.
The rest is a judgment only you can make. Fifteen thousand dollars for a one carat stone is many times what the same stone costs without the provenance, and seven to ten months is a long stretch of grief to hold open. Neither of those is a flaw in the company. They are the shape of the product.
If you want this, and you can afford it, Eterneva is where we would send you, and we would say so even if the price were lower elsewhere. If the number is out of reach, do not treat it as the only way to keep your pet close. A good urn, a set of solidified stones, or a pendant holding a small portion of ashes will cost a fraction and ask nothing of you but choosing it. There is no hierarchy of grief here, and no version of this that you can get wrong.
