Silver 925, also known as Sterling Silver, contains 92.5% silver and 7.5% copper. Pure silver is not used in jewelry making, as it is too soft. Silver has a seductive look with its warm color-temperature and has been used in jewelry making since ancient times. The disadvantage of silver is: It can react to sulfur in the air (depending on air quality and skin type). This is commonly known as ´tarnishing´ or ´oxidation´. The best way to remove these dark spots is the following: polishing cloth boil water in a pan and add some salt and a piece of uncoated aluminium foil. Then put your piece of jewel into the pan and "pickle" it wait for a while. Effective are also polish products especially made for silver-cleaning.

Surgical steel 316L, originally used in medical implants (e.g. artificial joints), has now become the most important material for piercings. It is characterized by its extremely shiny surface with practically no uneven traces. Surgical steel is also very scratch-resistant.However, it is not advisable to use surgical steel for first-time piercings since its nickel component as part of the alloy may become active when in contact with the sore salt of a newly pierced skin (we recommend to use Titanium G23 or Bioplast instead). Surgical steel can be worn without any trouble once the piercing hole is healed because Nickel cannot be absorbed by the body anymore. Allergies to surgical steel 316L are rare.

Bioplast is a biocompatible material, this means that the human body tolerates it completely. Since it is hypoallergenic, Bioplast is particularly suited for people wearing a piercing for the first time. When you purchase one of our piercing products for first time usage, please make sure to have your piercing sterilized by a professional piercing studio. Wearing bioplast enhances the healing process. In fact, the material flexibility guarantees an ideal adjustment to the pierced area. Bioplast navel piercings can be worn during pregnancy without any problem. Moreover, bioplast piercing barbells can shortened if necessary.

Zirconia (molecular formula: ZrO2, Zirconium dioxide) is synthetic substitute for diamond . Its hardness is almost as high as the one of diamond (8.5 as opposed to 10) which makes it resistable. However, it may scratch other material easily. Zirconia can be produced in different colours and levels of transparency. It is normally cut in faces (in the same way as glass).
