We use 316L Surgical Stainless Steel for majority of our body jewellery. Surgical steel does not oxidize or turn black, is corrosion and stain resistant and highly durable. While all steel does contain elements of Nickel which can cause reactions in some people, our 316L Surgical Steel is considered hypoallergenic due to only the smallest amount being present, and is extremely high polished. Polishing the jewellery to a mirror like lustre results in a protective layer which reduces the release of the nickel content into the tissue. Surgical Steel is safe for all body piercings, however those with extreme Nickel allergies are better suited to our pure titanium range.
