316LVM surgical steel and metal alloy Austrian crystal and Opal Claw-set External Eyebrow, rook, daith, and more! Each piece is sold individually. Where can you wear the PREMIUM Opal Halo Curved Barbell 16g? Almost everywhere - curved barbells are one of THE most versatile styles of jewelry we carry. This curved barbell is worn in surface piercings to get the look of studs. The perks of a curved barbell are that they move less through the piercing and catch on to fewer things than hoops do. This is why curved or straight barbells are preferred to captive bead rings and circular barbells for fresh piercings. The yellow and rose gold options are PVD. PVD is more durable and therefore longer lasting than traditional plating. However, this plating may irritate metal allergies. 316LVM surgical steel is hypoallergenic because it goes through low-carbon vacuum melting. This process sucks out the nickel from the metal. Nickel is one of the most common causes of metal allergies. Please note that this process cannot remove all the nickel and a very small number of people have reactions to 316LVM surgical steel. If this is you, we recommend our implant-grade titanium jewelry. We offer untreated, PVD-coated, and anodized titanium as hypoallergenic options. The charm is a metal alloy, which is ideal for casting and 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, metal alloy jewelry is recommended to be cleaned often and not worn in moist/sweaty places. This piece is a favourite for almost any piercing. Let's look at a few examples: daith, rook piercings, vertical labret piercings, vertical philtrum, eyebrow piercings, and so many more than we can list!
