Eterneva Review

Let’s jump right in.
What is Eterneva?
One look at Eterneva’s website, and you can catch their vibe. Despite working in a ‘heavy industry,’ the company has a sense of humor. They encourage customers to capture their loved ones’ essence in their jewelry designs.
However, there’s genuine backing behind their reputation. The company received funding from Tiger Management with participation from Mark Cuban, was featured in Forbes 30 Under 30, and won the Better Business Bureau Torch Awards for Ethics.
But the real story behind the company is what truly relates to customers.
Adelle’s Story
CEO and co-founder Adelle Archer’s mentor, Tracey Kaufman, was only 47 when she was diagnosed with pancreatic cancer. A senior executive at a tech company, she was afraid she would die before she had a chance to create a legacy. As the cancer spread, Adelle knew she had to do something to keep her memory alive.
Her idea? She would produce a black diamond from Tracey’s ashes, based on an inside joke.
“Tracey and I used to joke that she would throw me down ‘black diamonds’ of business challenges long before I was ready. So, when I heard about ashes to diamonds, I knew I wanted a black diamond to honor her,” Adelle said.
However, Adelle had questions about the process’s transparency. How would she know Tracey’s ashes were really in the diamond? Was the diamond even real?
These concerns prompted her to start her own ashes-to-diamonds company, with a transparent process that keeps customers apprised every step of the way.
How Does Eterneva Turn Ashes into Diamonds?
Eterneva provides a simple process for turning ashes into diamonds, including the following steps:
- Receive Your Welcome Kit: The kit includes a video, instructions, return postage, and the tools you need to send Eterneva your loved one’s ashes.
- Ashes to Diamonds: Once the ashes are received in a lab, they are placed in a graphite crucible to undergo carbon extraction and purification. Pressure and heat are applied, and a rough diamond emerges.
- Cutting, Grading & Certification: The diamond is cut by hand, and quality is assessed at every stage. It is then graded and engraved by Eterneva’s GIA diamond grader.
- Customized Design: When the diamond is ready, it undergoes the finishing touches. You can add natural color to the diamond, decide on an engraving, and choose a jewelry setting. The in-house designer will help you every step of the way.
- The Homecoming: Eterneva knows receiving your diamond is a special moment. They provide a special unboxing experience, which you can check out on their website.

If you are planning to transform your loved one’s ashes into a diamond, ensure you are prepared. Eterneva requires a ½ cup of cremated ashes or 5 grams of hair to make their diamonds. If you plan to split ashes with loved ones, make sure you have enough.
From there, they guide you through the process, providing everything you need to ship the ashes with their welcome kit. Special labeling may be required when sending ashes through the mail. It’s also advisable to store ashes in a cool, dry place prior to sending.

Eterneva’s Dedication to Transparency

Adelle understands from firsthand experience that customers may have doubts about their diamond’s authenticity. They offer a transparent approach, with the following techniques:
- Digital Ports: Each customer is assigned their own digital port so they can see exactly where their loved one’s diamond is at all times. They receive pictures and videos of the diamond-making process.
- Reports and Disclosure: They also receive a report and disclosure asserting the diamond was made from their loved one’s carbon.
- Guaranteed Quality Standards: Eterneva guarantees each diamond has a minimum clarity of SI2, though most are in the VS range.
- Tours: Eterneva is headquartered in Kerrville, TX, the largest memorial diamond facility in the United States, with additional sites in Switzerland and Germany. They welcome visitors to tour the facility and get a behind-the-scenes look at their operations.
Other Benefits
Transparency may be a primary reason to choose Eterneva, but that’s not all they offer. Here are some other benefits that set them apart in their field.
- Compassionate Staff: Eterneva understands they are part of the healing process, and they embrace that. Their compassionate staff provides an interactive experience throughout the healing journey.
- Tribute Videos: Eterneva’s tribute videos demonstrate their involvement in the customer journey, helping restore your loved one’s memory and celebrate their life.
- Storage Services: The company always asks for more ashes than they need. They store the additional carbon safely and securely, in case your diamond is lost, or you want additional diamonds made.
Positive Customer & Affiliate Reviews
Eterneva has received several positive customer reviews, including a 4.9 from Trustpilot. Most people appreciate the company’s dedication to customer service and transparency. But it’s clear that the meaning behind the diamond speaks louder than the service.
“It provides a source of brightness over a prolonged period of time,” founder Adelle says of the updates they send their customers.
Customer testimonials reveal what an Eterneva diamond means to them:
- “For me, it was all about keeping him close to my heart.”
- “Creating a diamond from your loved one’s ashes feels like she’s home in a way.”
- “Knowing my wife was here with me gave me the ability to heal.”
- “It’s a little bit of closure, and it helps.”
- “It’s an absolutely beautiful way to remember someone you love.”
Is There Anything Wrong with Eterneva?
So far, we have given Eterneva a glowing review, but there are some downsides to consider. For example:
- Cost: Eterneva is not exactly cheap. The cost of making a diamond from cremated ashes with Eterneva is 10-15 times as much as one made of other carbon atoms. It costs more because the diamond is created from particular materials. Additionally, Eterneva ensures high quality, customization, and great customer service.
- Are the Cremation Ashes There? Some argue that the remains from cremation are not sufficient to create real diamonds. However, this is up for debate.
- Critical Reviews: Although Eterneva has earned a 4.9 rating on TrustPilot, there are some critical reviews, mostly in terms of the extended timeline for receiving the diamond.
- Quality Issues: Eterneva guarantees your diamonds “will meet the carat weight your ordered and be free of visible inclusions’. However, they do not specify the diamond cut and color grades, factors that are critical in quality diamonds.

When purchasing a diamond, regardless of whether it’s a cremation diamond, natural or lab-sourced, always look for the right cut, to ensure it sparkles. Other factors to consider are the carat weight, color, and clarity. We also recommend only purchasing diamonds with a certificate to ensure their authenticity.

FAQs
Are cremation diamonds ‘real diamonds’?
Yes, cremation diamonds are real diamonds. They have the same chemical composition and physical properties as mined diamonds.
Should I send ashes or hair?
Both ashes and hair can be used to create cremation diamonds. If ash carbon is limited, or you prefer not to send ashes, hair can work. Some families send both.
How should I store for and care for ashes before sending?
Keep ashes in a sealed, sift-proof container in a cool, dry place. Avoid moisture and contamination. Label the container with a name and date. If humidity is a concern, add a silica gel packet.
