.905 Silver

 

At its core, it is a refined composition of silver and 901 Alloy.

 

Compared to traditional 925 sterling silver, .905 silver incorporates a greater presence of steel (901 alloy) — rather than conventional metals like copper or brass — to better balance structural stiffness with the flexibility required for crafting and molding. At the same time, it preserves the soul of the silver jewelry people have long been familiar with.

 

It preserves what matters most: With approximately 90.5% silver, the material retains the natural softness that allows our pieces to be molded, crafted, and finished by hand.

 

The remaining composition introduces the strength of 901 alloy — reinforcing the structure from within the core.

 

It is a deliberate balance between softness and strength, purity and endurance.

 

Together, they create a material designed not just to exist — but to evolve.

 

 

 

What is 901 Alloy?

 

901 alloy is not a traditional jewelry metal.

 

It is a chromium–nickel–iron based superalloy, originally developed for environments where materials must withstand extreme stress, oxidation, and long-term exposure without losing integrity.

 

It is engineered for:

  • High strength
  • Corrosion resistance
  • Structural stability over time

 

In other words — durability without brittleness.

By introducing this aerospace-grade alloy into silver, the material gains a quiet resilience that pure silver alone cannot achieve.

 

 

 

The intention

.905 silver exists for one reason: To allow jewelry to remain structurally strong, while still being emotionally alive by incorporating a much larger composition of steel into its core.

 

It holds form — but invites time.

 

And in doing so, each piece becomes not just worn, but formed.
