Casted Metals

Which materials are avalaible?

We at SHEYN decided to offer our pieces in three pure metals: silver, bronze, and brass. We believe in full, honest materials that can be restored to their original condition after wearing.

Sterling Silver

A soft, white, lustrous transition metal, silver exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. All our silver pieces are made from 925 Sterling Silver.


Brass is an alloy from copper, zinc and tin, resulting in a hard, corrosion-resistant metal. Polished it emits a gold-colored shine. Our brass consists of 15% zinc, 5% tin and 80% copper.


Bronze is an alloy made from copper and tin, creating a soft, rose-coloured shine. Is is polished until it creates the perfect shine. The brass pieces are made from 10% tin and 90% copper.


Patina and Shine

As our pieces are made from brass, bronze or silver, they react to the environment and to your skin. As a result, they might tarnish or lose their shine over time, just like all jewellery made from silver, brass or bronze. This is a natural process these metals are known for – some people also like the fact that their piece is changing its appearance over time.


The original condition and shine of the piece can be easily restored: Take the polishing cloth that comes with every purchase and polish the surface with light pressure. The cloth is coated in a polishing agent that removes the tarnish. We recommend to polish the pieces on a regular basis to keep the tarnishing to a minimum. You can find more information on cleaning your piece in this blog post.


Common behaviour

Some people might notice a small dark mark on their skin after they have worn a brass or bronze piece. This is a common and harmless chemical reaction, possible with all brass or bronze jewellery, and can be easily washed off. It is created by the combination of the metal and the acids coming from the skin. There are several metals that oxidise with skin and leave a dark mark: It is more common in brass and bronze, but even silver and gold metals can cause discolouration.

How to reduce the effect

To keep this effect to a minimum, we recommend the following: The use of lotions on the parts of the skin that will touch the jewellery should be avoided, as this can accelerate the reaction. Also, making sure that the piece does not get in contact with water (for example when washing hands, taking a shower or going swimming) will slow down the process.
