The Coffin + Cross Tunnel Hangers are matte black silicone and gold PVD over 316LVM surgical steel and metal alloy. The surgical steel is low vacuum-melted to remove nickel, one of the most common causes of metal allergies. This process cannot remove 100% of the nickel, however. As a result, there's still a chance those with severe allergies will react. PVD is more durable and longer-lasting than traditional plating. Those with allergies may react. If you are worried about metal allergies, we recommend looking at our anodized, blackline or untreated titanium jewelry. Finally, the matte black is a silicone finish and must be handled with care. If scratched or damaged, they may start to peel. 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 how you styled these earrings with #BodyModsFamous on Instagram.
