Enigmatic. Ingenious.

Join us on a journey of discovery.

We were immediately intrigued when we encountered this beautiful enigma: a double-sided central gold disc, paired toggles, and two removable gold discs that slide onto the toggles, all joined by a sturdy faceted cable chain. All with a velvety, smooth patina that only decades of human touch can create.

From the outset, we knew it had been made for Tiffany & Co. The familiar Tiffany mark on one toggle told us as much. But the piece still held more secrets. Closer examination revealed the faint France 18k mark on the opposite toggle, followed by tiny maker's marks that appear to match the Georges Lenfant export punch found on confirmed Georges Lenfant pieces in our personal collection. This attribution is further supported by the exceptional quality of construction and its manufacture for Tiffany & Co., one of Lenfant's distinguished clients during this period.

What first appeared to be a beautifully made curiosity revealed another surprise. We noticed a tiny, symmetrical gap at one end of the central disc where it connected to the chain. It was clearly not the result of damage or wear and appeared original to the design. After some trial and error, we discovered that the central disc is, in fact, a precision-engineered concealed clasp. To open, press firmly on the disc at the end opposite the tiny gaps. This releases the disc from its bezel, allowing the clasp to open. To close, simply slip the disc back into the bezel until it snaps securely into place. The engineering is remarkably simple and elegant—so much so that its function was not immediately apparent.

The paired toggles at each end are fitted with removable gold discs that resemble buttons. Together, they appear to have been designed to pass through two buttonholes, with the discs securing the toggles once in place. While we do not know the original application with certainty, it was clearly designed as an elegant and ingenious fastening device for a garment, perhaps a cape or sweater.

Whatever its original purpose, today it can be worn as a necklace extender, incorporated into a custom chain, or adapted in other creative ways by collectors who appreciate unusual mechanical jewelry. It is ideal for adding length and visual interest to vintage watch chains—or to other chains with end loops large enough for the toggles to pass through.

Whether admired as an ingenious mechanical object, an unusual example attributed to Georges Lenfant for Tiffany & Co., or a versatile jewel, this is a piece that rewards close examination. It is at once beautiful, tactile, and quietly clever—a testament to thoughtful design that transforms a functional object into wearable art.

Every new discovery only deepened our appreciation for this remarkable piece, and we would be delighted to see how its next custodian chooses to style it.

Marked Tiffany & Co. (one toggle), France 18k with copyright symbol (opposite toggle) — both marks very faint but discernible under magnification; additionally, tiny maker’s marks that strongly appear to be the Georges Lenfant export maker's mark (encountered less frequently than the workshop's French lozenge-shaped maker's mark).
