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.
MAGNETISM IN SURGICAL STEEL 316L
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.
A gemstone (also called a gem, fine gem, jewel, precious stone, or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli and opal) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.
