Jewel made entirely by hand by the Italian craftsman Gianmarco Fontana. Ring made of 925 silver, which is part of the "Animalia" collection depicting a jellyfish embraced on the finger.

The generic shape of a jellyfish is that of an inverted octopus. It can be imagined as a slightly flattened sac, where an upper convex area, the exombrella, and a lower concave region, called subumbrella, can be recognized, at the center of which is the mouth that connects to the gastrovascular cavity through a tubular structure called the manubrium ( handlebar). Stinging tentacles propagate from the sub-umbrella margin for defense and predation purposes.
Jellyfish have a body composed mainly of water (about 98%).
