A jewel designed to need one pair of hands.

Published 15 September 2026 · WHV · Public-source editorial note

A clasp is usually the part of a jewel that disappears from the story. With Hemmerle’s Harmony bangle, it is a good place to begin.

The clasp carries the idea

The design dates to 1991. In the house's account, a twisting mechanism allows the wearer to put the bangle on without somebody else's help. A small act of independence is built into the object. That is a more interesting starting point than counting the stones.

Harmony also offers a way to look beyond the usual hierarchy of precious materials. The 2017 example pictured here combines diamonds with iron, silver and white gold. Hemmerle’s archive includes other combinations, but they should be read as individual works rather than interchangeable variations of a standard investment product.

Read the individual work

The design's value lies in the relationship between the mechanism, proportion, materials and the body. A photograph can introduce that relationship. A fitting and a conversation with the atelier are better ways to judge whether it works for you. Hemmerle offers an enquiry route for current creations. The pictured archival bangle is identified as privately held, not as available stock.

For a secondary-market example, establish authorship, condition, construction, fit and any alterations. The value of the metal alone will not explain the price of a jewel whose interest resides in its making. Equally, the maker's reputation cannot tell you what your particular bangle will resell for.
