Sigillum
& Co.

Every letter a covenant. Every seal, a legacy.

Atelier
The Atelier

Born of an ancient
tradition.

In 1847, Édouard Sigillum established his atelier in the 6th arrondissement of Paris, three doors from the chancellery where Napoleon's dispatches had once been sealed. He made one thing: the impression that would close a letter and carry the authority of the sender across any distance.

In four generations, the craft has not changed. The copper dies are still cut by hand with a graver. The wax is still drawn from our proprietary formula, unchanged since 1923. The impression is still made with a single deliberate press — never twice.

"The seal does not decorate the letter. It validates it."

The Commissions

Three acts of impression.

I

The Crest Commission

A bespoke heraldic crest — designed from your family history, professional identity, or a chosen symbol system. Researched, drawn, refined, and cut into copper. Yours alone.

  • Heraldic research consultation
  • Three design iterations
  • Copper die, 40mm or 55mm
  • Certificate of uniqueness
II

The Signet Ring

An 18-carat gold or sterling silver signet ring, set with your commissioned crest or monogram. The stamp becomes jewellery. The jewellery becomes the stamp.

  • Crest or monogram design
  • Gold or silver casting
  • Engraving by hand
  • Matched wax sealing set
III

The Correspondence Kit

A complete sealing system: your stamp, your wax (three colours of your choosing from our 38 formulas), handmade envelopes, and correspondence paper in your house weight.

  • Brass or copper stamp handle
  • Three wax colours, 10 sticks each
  • 100 cotton envelopes
  • 50 sheets correspondence paper
From Commission to Correspondence

Four acts. Sixty days.

I
Consultation

A conversation about your identity, your intentions for the seal, and the impression you wish to leave. One to two hours. In person or by letter.

II
Design

Three iterations, each drawn by hand in our atelier. You approve one. We do not proceed until the design is exactly right — however long that requires.

III
Engraving

The approved design is transferred to copper and cut by a single graver. This takes between twelve and twenty hours, depending on the complexity of the design.

IV
Delivery

Delivered in a walnut presentation case with a first seal impression on handmade paper, wax-stamped and signed by the engraver. The beginning of your archive.

The Elements

The materials
of sealing.

Burgundy Classic

Our founding formula, unchanged since 1923. Deep wine-red with a hard, clean break. The default of serious correspondence.

Midnight Navy

A formal alternative to burgundy. Used by three European embassies and a legal chamber in Geneva since 1967.

Signet Gold

A warm 24-carat gold finish. Reserved for invitations and documents of unusual importance. Applied to the highest commission tier only.

Aged Parchment

A warm matte dark tan, the colour of old leather. Pairs exceptionally with cream cotton envelopes. A quiet choice for private correspondence.

Letters of Commission

From our archive.

From: Maison de Reuvens, Amsterdam

To the Atelier,

"The crest arrived this morning. My grandfather's motto, which I had only ever seen in a faded photograph of a document he wrote in 1941, is now in copper, and will press into wax at my hand for the rest of my life. I had not anticipated how strongly I would feel about this."

With sincere gratitude, — H. de Reuvens

Gentlemen,

"Every letter of introduction we have sent with the Sigillum seal has been remarked upon before the letter is read. The impression precedes the argument. That is, perhaps, the entire point of the enterprise — and you have understood it better than anyone I have worked with."

In admiration, — J.-L. Beaumont

To whom it may concern,

"In forty years of practice I have used three different seal houses. None of them cut copper at the level of Sigillum. The detail in a 40mm die that I would not have thought achievable. Our clients have noticed. Two have subsequently commissioned their own."

Sincerely, — V.R. Thornton, Barrister
