Find here all the information about the material of your SHEYN piece and how to take best care of it. Our current collection consists of 925 Sterling Silver and 3D-printed steel, while older collections were also offered in brass and bronze.
All our silver jewellery is made from 925 Sterling Silver, consisting of 93% silver, 4% copper and 3% zinc. Pure silver relatively soft, so it is alloyed with copper and zinc to increase its hardness and strength. The material naturally oxidises over time by exposure to the air and contact with the skin, but can be easily restored to its original condition.
Our pieces made from 3D-printed steel are made from steel powder in a binder jetting process and are then infused with bronze. The final mix is composed by a variable range of 60% steel and 40% bronze. That’s why the material colour can range from a silver grey to a reddish bronze – bringing a unique colour to each piece.
Brass is an alloy from copper, zinc and tin, resulting in a hard, gold-coloured metal. Our brass consists of 80% copper, 15% zinc and 5% tin. The material naturally oxidises over time by exposure to the air and contact with the skin, but can be easily restored to its original condition.
Bronze is an alloy made from copper and tin, creating a sturdy metal with soft, rose-coloured shine. Our bronze pieces are made from 90% copper and 10% tin. The material naturally oxidises over time by exposure to the air and contact with the skin, but can be easily restored to its original condition.
Patina and Shine
All polished pieces made from made from silver, brass or bronze 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 these materials. To slow down this process, we recommend to store the products inside the SHEYN case and to avoid the contact of the piece with water, soap or lotions. The original colour can be easily restored with a coated jewellery polishing cloth or a silver bath.
The original condition and shine can be easily restored with a coated jewellery polishing cloth. Take the polishing cloth 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.
REACTION WITH THE SKIN
Some people might notice a small dark mark on their skin after they have worn a brass, bronzer 3D-printed steel piece. This is a common and harmless chemical reaction, possible with all brass or bronze jewellery, and can be easily washed off.
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.
