Surgical Steel is the safest material to use, however if you are not allergic to precious metals, gold may be used also.
The term "surgical steel" is for the most part a little bit of a misnomer. Body jewelry is classified as "implant grade steel", but in any event, there isn't a lot of difference between the two other than the fact that implant grade steel will never break down and corrode in the body as stainless can do over time. Rarely body jewelry is made of stainless steel, but plugs for ears are sometimes made of it.

Surgical steel earrings can be purchased at jewelry and fashion sites such as Etsy, Polyvore, and FreshTrends as well as department stores such as Amazon. The steel in these earrings is 'surgical' because it is specially made to guard against infections, which is important for a body piercing.
Cheap body jewelry is just as good as high-end jewelry if made from stainless steel.
If you purchase high-end body jewelry or body jewelry made with precious metals such as gold, titanium, silver, etc then it can last for a very long time (20-40yrs). Purchasing fine body jewelry is a kind of investment, not an actual expense. Also, wearing high-end body jewelry is very safe for the body. So yes if you pay more for it you will definitely get more. You can search the "FreshTrends"(the fine body jewelry seller) on google for high-end body jewelry with amazing designs.

Bioplast jewelry is jewelry used for body piercings. Bioplast jewelry is made up of different types of plastic. This makes it more compatible than metal for body piercings as some people are allergic to certain metals.
To quote a somewhat famous piercer, JC Potts, "saying surgical or surgical stainless is like saying space-age plastic." Most steel used in a medical setting is 316L stainless or 316LVM ASTM F-138 Implant Grade, which is what most proper steel body jewelry is made of as well. If the jewelry is being promoted as "surgical" or "surgical stainless," I would be wary of it until I knew for sure it was one of the above types, as it could very well be made of lower quality steel and simply be marketed with flashy sounding titles to lure in the uneducated.
