Just click and go! 316LVM surgical steel is hypoallergenic because its low carbon vacuum melted. This process sucks out the nickel from the metal. Since nickel is one of the most common causes of metal allergies, this makes it hypoallergenic. Please note: this process cannot remove all the nickel. As a result, a small number of people react to 316LVM surgical steel. If this is you, we recommend going with the blackline titanium option. Titanium is hypoallergenic and bio-compatible. Its often used in medical implants because of these traits. The black is titanium carbide as a physical vapour deposition (PVD) coating. The titanium carbide is deposited onto the titanium as a vapour. This process does not affect the piece's hypoallergenic status. The gold option is PVD. PVD is more durable and therefore lasts longer than traditional plating. The plating may irritate metal allergies. 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. These Crystal Chain Cuff Earrings are 18g and will fit comfortably in any standard ear piercing. Please check the diameter to ensure they will fit around your lobes.
