316LVM surgical steel and metal alloys Austrian crystal Claw-set Internal Lip, medusa, ears, and more! This labret post is 316LVM surgical steel! 316LVM surgical steel is a low carbon vacuum melted. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. PVD stands for Physical Vapour Deposition. In other words, the colour deposits onto the metal as a vapour. As a result, the metal looks black, gold, or rose gold. Yellow and rose gold coatings may cause reactions. Metal alloys are ideal for casting, which makes them perfect for jewelry with fine details. Many people have sensitivities to these alloys and may react. Metal Alloys with a PVD coating can help negate this reaction, but they may still irritate those with the strongest sensitivities. To avoid turning green, it is recommended that brass jewelry is cleaned often and not worn in moist/sweaty places. As we mentioned at the beginning, the PREMIUM Crystal Starburst Labret is a favourite for SO many piercings. Here are a few examples: philtrum (aka medusa) piercings, lobes, conch piercings, helix, lip piercings, tragus, and so many more than we can list!
