Von Rumpel’s search for the Sea of Flames

Reinhold von Rumpel’s search for the Sea of Flames is a pursuit shaped as much by uncertain provenance as by physical obstacles. The diamond is concealed within a museum’s systems of protection and wartime dispersal, while copies and incomplete records make possession difficult to distinguish from evidence. His trail leads from a guarded museum safe to private collections and finally to a miniature of Paris that appears to be a container in its own right.

Origins of the search

As war approaches, the Muséum national d’Histoire naturelle moves to protect its collections. Couriers carry objects toward country estates; crates are padlocked, manifests secured, and armored trucks arrive at the loading docks. Fossils and manuscripts are among the material being safeguarded, alongside objects such as jade, Indian cavansite, Colorado rhodochrosite, pearls, gold nuggets, and a sapphire described as being as large as a mouse. Amid this inventory, Marie-Laure considers that the Sea of Flames may also be among the threatened treasures. The diamond’s possible presence belongs to a wider emergency of securing and relocating collections, not to an isolated mystery detached from the institution around it.

The museum’s plan deliberately complicates the chain of custody. Three decoys are made in addition to the real diamond: one is to remain at the museum, while the others are sent in different directions. One travels south with a young geologist, another north with the chief of security, and a third is carried by Daniel LeBlanc, the museum’s principal locksmith, in his tool case in a field west of Versailles. The arrangement spreads risk, but it also multiplies the possible locations of the jewel and the number of objects that might be mistaken for it. Protection depends on concealment; concealment, in turn, creates uncertainty for anyone trying to establish what is real and where it went.

The museum and its layers of concealment

Von Rumpel’s access to the museum’s hidden spaces passes through a sequence of barriers rather than a single locked door. A small door at the back of the main-floor gallery requires two keys. The assistant director appears unfamiliar with its lock, but opens it; the party then descends a winding stone staircase and passes through a second gate. Beyond corridors and a warder’s station, they reach an unassuming storeroom crowded with dropcloths, pallets, and crates. Behind a plywood sheet sits a combination safe, which the assistant director opens with relative ease. The route makes the institution’s protective architecture concrete: access is controlled by keys, gates, corridors, personnel, and concealment, yet the final barrier can be opened by someone with the necessary combination.

The contrast between the elaborate approach and the plain storeroom gives the search its characteristic tension. Security does not make the collection transparent to its guardians or to the reader; instead, each protected layer raises the question of what is held behind it. The safe’s opening is a decisive step in the pursuit, but the evidence of the route is also evidence of how much institutional knowledge is required to reach the object. The search is not simply a matter of recognizing a jewel. It depends on reconstructing which people, safeguards, and transfers connect the object to its supposed location.

Copies, testimony, and scattered records

The distinction between original and replica becomes especially consequential in von Rumpel’s inquiries about Dupont, who made three replicas for the museum during the two months before the invasion of France. Dupont says he used a casting rather than the real diamond and never saw the original. Von Rumpel believes him. That account gives the search a limit as well as a clue: the maker’s testimony can explain how copies were produced, but cannot establish the original’s whereabouts through firsthand inspection. The replicas expand the trail without resolving it.

Other records arrive indirectly. In a hotel, von Rumpel receives a package from a librarian in Vienna containing copies of Tavernier and Streeter and stencil duplicates of de Boodt’s 1604 Gemmarum et Lapidum Historia, written in Latin. The librarian has gathered everything she could find concerning the Sea of Flames, but the resulting material amounts to only nine paragraphs. The books supply a documentary trail rather than a direct answer. Their arrival shows the search reaching beyond the museum and drawing on scattered scholarship, while the small quantity of relevant text underscores how little firm information the available sources provide.

The search also proceeds through private collections and locations tied to earlier wartime flight. Von Rumpel travels for the first time since completing treatment in Stuttgart to a warehouse outside Lodz. There, behind razor wire and six guards, he changes into a pocketless jumpsuit. Three dead bolts separate him from four enlisted men in matching suits, each stationed at a table with a jeweler’s lamp. The windows are covered with plywood. A padlocked sack is opened and its contents poured onto a velvet-lined tray: thousands of jewels, including emeralds, sapphires, rubies, citrine, peridot, chrysoberyl, and hundreds of small diamonds, many still set in jewelry. The scene places the sought-after stone among an immense quantity of potentially valuable objects, making inspection a problem of discrimination as well as access.

Following objects into private spaces

Another lead takes von Rumpel to a château outside Amiens, where he believes the chief of security at the Paris museum fled after the invasion of France three years earlier. The house belongs to a retired paleontologist and stands among fields and hedges. In the library, von Rumpel finds that a bookshelf has been peeled open to reveal a strongbox. He opens it with a stethoscope and without a flashlight. The search thus follows the museum’s former security chief into a domestic collection, where institutional concealment has given way to a hidden compartment inside a private library. The location suggests a route of wartime displacement, though the evidence here does not establish that the diamond is in the strongbox.

At the Apartment on rue des Patriarches, von Rumpel offers ration tickets to the landlady and enters a cluttered, old-fashioned flat. In a work area he finds tiny benches, lampposts, woodworking tools, nails, and hardened glue. Beneath a dropcloth is a detailed model of the Paris Fifth Arrondissement Model: its buildings are unpainted, but its shutters, doors, windows, and storm drains have been carefully rendered. The model contains no people. At first it presents itself as a toy or an intricate representation of a neighborhood; on its underside, however, von Rumpel finds a small hole resembling the keyhole in the museum jewel safe he had seen three years earlier.

That resemblance changes how he reads the model. He recognizes it as a container, turns it over, and tests its bottom and sides while trying to solve it. The search has moved from large-scale institutions and guarded repositories to a crafted object small enough to be handled, but the habits remain the same: observe a lock, compare it with an earlier one, and infer hidden storage from physical design. The evidence ends with him still working at the problem. It establishes his recognition that the model conceals something, not what he ultimately retrieves from it.

Significance of the pursuit

Von Rumpel’s search links the Sea of Flames to the vulnerabilities and procedures of collecting: cataloguing, replication, secure storage, evacuation, private custody, and the testimony of people who may know only part of an object’s history. The diamond is repeatedly approached through intermediaries—a director’s plan, a locksmith’s tool case, a maker’s account, a librarian’s copies, a security chief’s presumed refuge, and finally a model with a concealed opening. Each lead provides a piece of the chain without making the chain complete.

The repeated distinction between the gem and its representations also gives the pursuit a material logic. A casting can produce convincing replicas without the maker ever seeing the original; a model can represent a real district while functioning as a receptacle; a safe can protect an object while leaving its identity dependent on records and access. Von Rumpel’s method is to treat every barrier and artifact as evidence, but the search’s successive settings show why evidence is not the same as certainty. By the time he reaches the miniature, the question is no longer only where the Sea of Flames has been sent. It is also how a hidden object can be recognized when copies, transfers, and concealment have broken its history into fragments.
