Surgical Steel 316

SS316L is a surgical implant grade, which is the most used material for Body Jewelry. The two most common standards that apply to body jewelry made of steel are ASTM F138 and ISO 5832-1 which describe the qualities of steel for surgical implants.

The element in stainless steel that causes allergic reactions in some people is nickel. Polishing the jewelry to a mirror like luster results in a protective layer of chromium oxide, which reduces the release of the Nickel content into the tissue. Surgical Steel can be sterilized in an autoclave.

Check certificate and nickel release certificate for more info. You can also check the latest European directive regarding the use of nickel for body Jewelry.


We had some returning questions regarding magnetism in Surgical Steel 316L. Some people still believe that if the steel is magnetic then it is not surgical steel. We would like to emphasize here one more time that this is not true. Stainless Steel 316L is a low-carbon form of 316 steel. Although it is non-magnetic when produced, it may become magnetic when worked.

Lab Created Opals

Lab Created Opal (GIA: Polymer Impregnated synthetic opal) is impregnated in the laboratory in around a year and has similar properties as that of natural opal. The main difference with natural opal is that the naturally occurring process has been sped up in the laboratory. Our Lab Created Opal is a beautiful opal with a perfect color dynamicity - revealed the beauty of Precious Opal.

Opal material from the KYOCERA Corporation in Japan is composed of at least 80% Silica and is exhibiting beautiful and vivid opal colors.

This material should not be mistaken with Opal-like plastics sold as imitation or fake Opals. Those materials contain mostly 80% Resin and only 20% Silica. Therefore, they do not qualify as «Lab Created Opal ».
