Eterneva Review: Are Their Cremation Diamonds Worth It?
Eterneva grows real lab diamonds from the carbon in cremated ashes, and it has become the best-known name doing it. Here is what it costs, how the process works, and our honest take on who it suits.
Who Eterneva is
Founded in Austin, Texas, Eterneva turned memorial diamonds into a mainstream idea, helped by a Mark Cuban investment and heavy press coverage. The company is BBB accredited with an A+ rating and no complaints on file, and won a BBB Torch Award for Ethics.
What it costs
Pricing starts around $2,999 and climbs steeply with carat and color: a 0.25 carat stone runs about $3,499, and larger or colored diamonds reach $25,000 and beyond. Payment plans start at roughly $188 a month. Settings for rings or pendants are extra.
The process and the wait
Eterneva needs about half a cup of ashes, from which it purifies roughly a gram of carbon, grows the diamond under high pressure and temperature, then cuts, grades (IGI certified) and sets it. The full journey takes seven to ten months, with photo and video updates at each stage, which customers consistently praise.
Our verdict
The experience is genuinely excellent and the diamonds are real and certified. The trade-offs are the price, which buys a modest natural diamond several times over, and the wait of most of a year. If those are comfortable, Eterneva is the strongest name in the category. If not, diamond-set cremation jewelry delivers sparkle around the ashes themselves for a few hundred dollars.
Our picks
The affordable alternative
If the lab-diamond price is out of reach, these pieces set real diamonds around a sealed chamber of your loved one's ashes, ready in weeks rather than months.
