“They need something more meaningful that eases the grief”
Eterneva grows diamonds from cremated remains and turns them into jewelry that can be worn as a lasting memorial.
Cremation ash – or hair – contains 0.5–4% carbon, enough to grow a lab diamond. The process takes 7–10 months end-to-end: extracting the carbon, growing the crystal, applying color if the client wants it, and then crafting the finished piece.
Prices start at a few thousand dollars and climb to $50,000, depending on the desired carat weight and color. Since the startup launched in 2017, it has grown 1,500 diamonds for 1,000 clients – which means some customers came back for two or three stones.
The startup's first investor was Marc Cuban, well known as a shark on the TV show Shark Tank. He returned for the latest round as well.
One figure worth flagging: 40% of Eterneva's business comes from memorial diamonds grown from the remains of pets.
"We all die" is an overused line – but as a business observation, it's hard to argue with. The death market is, by definition, the entire human population.
The problem is that the traditional end – cemeteries, funeral homes – is saturated and effectively locked up. So newer entrants approach it from different angles: estate planning, memory preservation, grief communities. Eterneva staked out an unusual corner: turning death into something beautiful and permanent.
If the subject weren't so inherently sad, you'd call this sharp marketing – capitalizing on advances in lab-grown diamond technology to offer a product that's both emotionally resonant and now accessible at scale.
What makes the model smarter than it first appears is the 7–10 month production window. Eterneva doesn't just take an order and ship a ring. It invites families to send photos and share memories of the person who died – turning the wait into an extended, intentional process of mourning and remembrance.
That nearly year-long journey becomes something traditional funerals can never provide: time to process. "People no longer want the traditional funeral," says the co-founder. "They need something more meaningful that eases the grief – and we plan to keep expanding the concept with new products and services."
The big-picture takeaway is simple: the death market is wide, permanent, and largely underserved beyond its traditional players. Cemeteries and caskets are not the whole story.
A more direct path is to look at what Eterneva built and ask whether a similar model – unusual, emotionally charged, premium-priced – could work in your context. It's a model that looks exotic at first glance but turns out to have real depth.
