One of the most important aspects of getting a piercing is choosing a safe metal that won’t cause reactions or allergies. You’ll often see niobium and titanium on the list of safe metals to use for fresh piercings due to their bio-compatible properties.
But if these two metals have been anodized, which they often are, do they still remain safe for piercing jewelry?
Keep reading as we cover this topic in depth.
If you don’t want to stay with us till the end, then here’s a quick overview that summarizes the benefits of anodized titanium and niobium.
Quick Overview: Pros of Anodizing Metals:
What is Anodizing?
Not every metal can be anodized, as some metals just react differently to the process. Titanium, niobium, zinc, aluminium, magnesium and tantalum are able to undergo the process. Of this selection of metals, only the first two are suitable for body piercings. Most other metals just exfoliate when anodized, meaning that the surface layer will peel off.
During the anodizing process, a film or coating is formed on the surface by heating the metal. The heating process is done by introducing electricity to the metal which results in a permanent surface change.
In the case of titanium and niobium, anodizing causes the natural oxide layer on the surface to thicken and the miniscule debris found on the surface of the metal is removed by the process, resulting in a smoother texture.

How Do Anodized Metals Get Their Colors?
What makes anodized metals so special is the array of rainbow colors that they display without the use of any dyes. Both niobium and titanium can display gold, green, purple, copper, yellow, blue and sometimes even an oil slick effect.

The stunning patterns and hues are all natural, caused by the light interfering with the oxide layer and creates the color. If there was no light during the process, there would be no colors.
Both niobium and titanium anodize in a similar way. During the process a layer of oxide forms on the surface of the metal, which interacts with light and creates an array of iridescent colors.
The colors that the metal displays depend on how thick the oxide is, which in turn depends on the voltage of the current during the anodizing process. This makes the anodizing process a work of art, and sometimes, getting the exact same color again can be tricky.
Are Anodized Metals Safe to Wear?
Not all anodized metals are safe for piercings but anodized titanium and niobium are hypoallergenic and safe to wear. They won’t cause skin reaction so allergies of any kind, making them an excellent, bio-compatible option for even fresh piercings.
People worry when they see the lustrous colors of the metal and immediately assume that it’s not safe to wear for fresh piercings. They tend to think it’s a type of plating but unlike plated metals, anodized metals don’t flake or peel. It hasn’t been dyed, plated or coated with any other substance. Even though there are other colors on the surface, the metal is still either titanium or niobium all the way through.
Something to watch out for is metals like stainless steel that have been given a titanium coating. These are be sold as Titanium Anodized but may not be hypoallergenic or safe to wear. Always check this carefully and make sure that the entire piece of jewelry is made of titanium or niobium.
Do Anodized Metals Change Colors?
Over time, you might notice that the vibrant colors of the anodized metal may start to fade. This is merely because the oxide layer is starting to wear off and get thin, exposing the natural color of the metal. However, while it may slowly wear off, it will never flake off. This process is not unsafe and poses no harm to your body.

Anodized metal jewelry is durable and easy to maintain. Following some reasonable tips will ensure that the jewelry remains lustrous and colorful for a long time.
Where to Buy Anodized Body Jewelry?
Taking your search online will open up a range of options to choose from. To buy jewelry, especially for piercings, you can try looking up a shop that specializes in this type of jewelry or you can search through sites like Etsy and Amazon, which have endless options on offer.
Most of the specialist shops offer their products via these two major platforms, so you’ll probably find most of them in the same place.
Just ensure that the materials are 100% safe. As already mentioned above, if you’re choosing titanium, make sure that the metal is, in fact, anodized titanium and NOT other metals anodized with titanium.
