Eterneva
A pair of entrepreneurs who have come up with a way to help people to remember their loved ones after they're gone: by freezing them in carbonite by turning their ashes into diamonds.
While, at first, Mark accused them of merely coming on the tank as an advertisement and not looking for an actual deal (something Daymond had words for them about), they eventually did make a deal with him.
However, following the episode, there has been some controversy over whether pressing a person's ashes into a diamond is even possible. This deal is being collated and will soon be posted. Check back shortly to see the details on this company and the pitch it made on Shark Tank.
