High End Jewelry

High End Designs from Engineer's Jewelry are defined by a composition of multiple parts to enable functionality.
The precious metal pieces are assembled with industrial steel bolts and nuts, that become part of the theme.
While the use of such means are no option for conventional jewelry, this unique approach presents the special charm of the technical designs.


Most of the here shown themes can be realized as attachments for tie bars, as cufflinks, or even pins.
There are almost no limitations to the customer's request.

The shown jet engine made of spinning fan rotor and stationary fan case is assembled by a ball bearing and includes many details.
The design is available as cufflinks or tie bar.

The rotor is characterized by 20 fan blades with realistic aerodynamic shape, as well as details representing the spinner cone's bolting. The casing is modelled after real jet engine nacelles.
A striking appearance can be achieved by chosing different materials or platings of the two parts, which also underlines the special functionality at first sight.

The stator unit includes a correctly oriented stage of stator blades in bypass and core section of the engine. Outside of the bearing chamger are the IGV (Inlet Guide Vane) blades with high aspect ratio (cord length / blade height) which guide the air to the high pressure compressor. Radially outside the ring shaped lip are the fan stage stator blades.
Therefore even the cufflink's rear side is defined by a realistic appearence with correct architecture.

Multi Part

The main feature is the assembly of each cufflink from the two parts rotor (fan) and stator (fan case) with a bearing chamber, thus creating a rotating, functional modell. Applied means are bolts, ball bearings, elements such as washers and nuts as well as a specially designed retaining ring made of spring steel for the union of the parts.


Choice of materials for both parts is diverse.

For disk and caliper the materials bronze, brass, silver, 14 karat normal, rose and white gold, and 18 karat gold are available, as well as precious plated brass.


precision cast pieces


special retaining ring
(spring steel)

An M 1.6 hex key bolt connects the pieces fan rotor and case.

A ball bearing is secured in the support structure housing with a retaining ring.

This ensures an authentic and wear-resistant assembly in tight space.

The Closure

All High End series pieces from Engineer's Jewelry feature a thick round counterpart with groove.
It creates a high quality look and feel, completed by a black o-ring for another unique element.

The rod is unlike anything else ever concieved, due to a longitudinal hole which serves as the acces to the bearing chamber assembly. It is strengthened with further material but still also includes the typical Engineer's Jewelry lightweight holes.
