Eterneva turns cremated remains, human or pet, into lab-grown diamonds, a pitch that made more than one shark visibly uncomfortable back in Season 11. Mark Cuban was not one of them. Years later, the company he backed has grown into something closer to a legitimate memorial-industry disruptor than a novelty product.
The Short Answer
Eterneva is still in business and has grown considerably since its Season 11 appearance. The company reports approximately 6.5 million dollars in annual revenue and raised a 10 million dollar Series A funding round in 2021, well after the Shark Tank episode aired.
You can order directly through eterneva.com, which remains the company's primary channel. This is not a product you'd expect to find on Amazon given the deeply personal, custom nature of the service, and it does not sell there.
The Shark Tank Pitch
Eterneva pitched in Season 11, Episode 3, in the business services category. The company's process takes carbon extracted from cremated ashes, or in some cases hair, and grows it into an actual diamond, giving families a permanent physical way to hold onto a loved one, a service that extends to pets as well as people.
The founders asked for 600,000 dollars for 5 percent equity, valuing the young memorial-diamond company at 12 million dollars going into the Tank.
The Deal That Got Done
Mark Cuban closed the deal, agreeing to the full 600,000 dollars requested but taking 9 percent equity instead of the 5 percent on the table. It was a modest equity bump for Cuban to secure the investment, and Eterneva has gone on to become one of the more visible successes in his Shark Tank portfolio.
Cuban's willingness to back a product this unconventional, effectively a grief-tech and memorial company, signaled early that he saw a real, underserved market rather than a novelty pitch.
Building Out Real Infrastructure
The clearest sign that Eterneva is a serious operation rather than a boutique curiosity is the lab infrastructure it has built since the show. The company describes operating what it calls the most advanced memorial diamond lab in the world, a facility built out after the Shark Tank appearance, not before it.
That build-out extended internationally, with facilities established in Switzerland and Germany, giving the company production capacity and reach well beyond a single U.S. location. Along the way, Eterneva picked up coverage in Forbes, Inc., Time, and Fast Company, press attention that goes beyond the typical Shark Tank alumni writeup and into genuine business-press interest in the memorial-diamond category itself.
The company has also built a client base that includes celebrities, alongside ordinary families who have used the process to honor parents, spouses, children, and pets. That range, from famous names to grieving families finding the company through word of mouth, is part of what has sustained demand years past the initial television bump.
Eterneva net worth in 2026
Eterneva's most concrete financial data points are the 6.5 million dollar annual revenue figure and the 10 million dollar Series A round closed in 2021, both reported by Shark Tank tracking sites and business press. Those two numbers, taken together, suggest a company valued well above its original 12 million dollar pitch valuation, assuming the Series A round priced the company at a meaningful step-up, which funding rounds typically do.
No source publishes a specific 2026 net worth figure for Eterneva as a private company, and none should be assumed. The revenue and funding figures are the verifiable data points; anything beyond that is estimation.
Where Things Stand Now
Here is the recap. Eterneva pitched in Season 11 asking for 600,000 dollars for 5 percent, and Mark Cuban closed the deal at 9 percent instead. Since then, the company built out international lab facilities, raised a 10 million dollar Series A, and grew to roughly 6.5 million dollars in annual revenue.
For a company built around turning ashes into diamonds, a premise that could easily have stayed a one-episode novelty, Eterneva has instead built the kind of infrastructure and press profile that points to a real, growing business. If you're wondering whether it's still around, the answer is yes, and it looks stronger than it did on the day it pitched.
