Ostona Electronic Key

mokume-gane (gold, silver, copper), diamonds

Price on request

Handcrafted · Passport and serial number · One-of-a-kind pattern

An electronic access key housed in mokume-gane — a layered bond of gold, silver and copper. A line of diamonds runs along the edge of the case, dividing the two planes of the pattern. The figure belongs to the alloy itself. The layers run through the full thickness of the case, so daily carry does not wear the pattern away — it draws it deeper. No two keys can hold the same figure; each receives its own. The chip and antenna remain original, and the case does not affect the access system. Each key is made for your system — send us the model of your key or fob, and the master will confirm compatibility before work begins.

How it is made

Our master jewelers handcraft unique creations using the techniques of Mokume-gane and Damascus steel, where metal transforms into art.

Mokume-gane is a fusion of noble metals whose intricate patterns resemble natural wood grain. By combining this method with the tradition of Damascus steel, we create pieces with true character — durable, noble, and one of a kind.

Questions and answers

How is mokume-gane different from Damascus steel?

Both techniques are based on working with layered materials, but their composition and purpose are fundamentally different.

Damascus steel is traditionally made from steel and is used primarily for blades. Its contrasting pattern emerges from differences between the steel layers and subsequent surface treatment.

Mokume-gane is made from coloured and precious metals and is valued primarily for its unique visual pattern, which emerges as the inner layers of the material are revealed.

Does mokume-gane darken over time?

This depends on the metals used. Copper and its alloys darken over time, while gold and silver undergo comparatively little change. The contrast of the pattern generally becomes deeper with age.

How many layers are there in mokume-gane?

The number of layers depends on the technique and the purpose of the object. Smaller works may contain only a few layers, while more complex billets can contain several dozen.

The number of layers affects the density and character of the future pattern, but a greater number of layers alone does not determine its complexity. The thickness of each layer and the method of subsequent deformation also play an important role.
