The Vanished Diamond

The Vanished Diamond is an 1884 adventure and science fiction novel credited to Jules Verne, based on an uncredited manuscript by Paschal Grousset. It belongs to Verne's Voyages Extraordinaires series and was originally written in French. From the available details, this is the kind of Verne story that combines a clear speculative idea with movement, pursuit, and tension, rather than deep character study. The title points to a central object and a sense of disappearance, but the book is best understood here as a compact example of Verne's adventure-driven fiction.

This is a good fit for readers who like early science fiction with a practical, exploratory feel, and for anyone curious about a less commonly discussed Verne title. It should work well if you want a story that stays close to the mechanics of discovery and the pace of an adventure plot, without aiming for heavy literary effect. Its natural connection is to the rest of Voyages Extraordinaires and to late 19th century science-driven adventure fiction in general.
