316LVM surgical steel and PVD metal alloy Austrian crystal and opal Claw-set External 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. Otherwise, 316LVM surgical steel is excellent for people with metal allergies. 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 metal alloy jewelry be cleaned often and not worn in moist/sweaty places. The stones are lab-grown opal. These are our favourites because they are more durable than natural opals. Being lab-grown also makes them a more ethical choice. Additionally, they can go in an autoclave. As we mentioned initially, the PREMIUM Opal Petals 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!
