Jewel made entirely by hand by the Italian craftsman Gianmarco Fontana. Ring made of 925 Silver depicting Ninja Turtles, which is part of the “OTAKU.

Ninja Turtles are four anthropomorphic mutant turtles, greedy for pizza and raised in the sewers of New York, trained in the martial art of ninjutsu by Hamato Yoshi, aka Splinter, a former martial arts master.
The turtles acquired a humanoid appearance when, in the state of aquarium turtles, they came into contact with a mysterious chemical compound poured into the sewers, in which they accidentally ended up; since the last being they had been in contact with was a human, they were transformed into humanoids. Even Splinter, finding himself in the sewers due to the conditions of poverty in which he lived, came into contact with the compound, transforming himself into the image of the last living being with which he had come into contact; Yoshi in his misery had mice for companions, and became a large anthropomorphic mouse.
Having laid down the name of Yoshi and adopted that of Splinter, the old master adopted the young turtles, having always been a lover of animals, and being also passionate about art, he baptized them with the names of four Renaissance artists: Leonardo da Vinci, Raffaello Sanzio , Michelangelo Buonarroti and Donatello. The turtles lead a reserved life in large sewers, fearful of being pointed to monsters by the human population and discriminated against; when they rise to the surface they usually disguise themselves summarily with a raincoat and a Borsalino hat.
Together they fight the diabolical Shredder, Splinter's old rival, and archenemy of the Turtles transformed into a supervillain wearing metal armor full of blades, inspired by that of the Japanese samurai. Shredder commands the clan of the foot, an army of robotic ninjas, and with the unwelcome help of Krang, a treacherous amorphous alien with superior intellect, he plots to conquer absolute power.
