This process sucks the nickel from the metal. Nickel is a common cause of metal allergies. 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 titanium body jewelry. The pineapples have PVD with yellow gold. PVD is more durable and therefore lasts longer than traditional plating. However, 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. Show us where you wear yours with #BodyModsFamous on Instagram.
