Eterneva announced a $10 million Series A on July 26, 2021, led by Tiger Management, with Mark Cuban among several co-investors. The funding is historical news—not a new raise. Eterneva’s current service turns carbon it says it extracts from submitted ashes or hair into a memorial diamond; the company currently lists a 10–12-month timeline and prices ranging from $3,499 to $75,000.
What happened with Eterneva’s $10 million raise?
On July 26, 2021, Eterneva announced that it had closed an oversubscribed $10 million Series A. Tiger Management led the round. The company named Goodwater Capital, Capstar Ventures, NextCoast Ventures, Mark Cuban and others as co-investors in its announcement.
The announcement is the basis for the “Mark Cuban-backed” description: he was one of the named co-investors, not the lead investor. Eterneva’s About page says it appeared on Shark Tank in October 2019 and that its founders built the company after a founder’s mentor died. The company also says it has invested more than $15 million in infrastructure and research and development for its Kerrville, Texas, facility; that figure is a company claim, not an independently audited investment total.
How does Eterneva say it makes a memorial diamond?
Eterneva describes its service as using carbon extracted from a customer’s submitted ashes or hair to grow a diamond. Its welcome-kit page says the customer sends roughly half a cup of material. The company describes transferring it to a graphite crucible, purifying the carbon, and growing a diamond in high-pressure, high-temperature conditions. It says the finished stone is inspected for inclusions and cut into the requested shape. Customers can choose size and color, and Eterneva says it can help with selecting a setting near the end of the process.

Is a memorial diamond a financial or grief-care solution?
It is best understood as a personal keepsake, not an investment with an established resale value or a substitute for financial planning. The available company pages do not establish what a finished stone could be resold for. Eterneva presents the service in the context of remembrance, but the sources cited here do not establish that buying a memorial diamond treats grief or produces a clinical mental-health benefit. Families should weigh the expense against their own priorities and budget.
