Yes, we offer a dedicated collection of Certified Hypoallergenic Implant-Grade Titanium (Ti-6Al4V-ELI) cartilage earrings which are nickel free. Our jewellery is certified by AnchorCert analytical laboratory - all certificates can be found here.Hypoallergenic is a term used to define a product that has reduced chance of causing an allergy. There are varying degrees of skin sensitivity but Titanium is the best option for most with sensitive skin. Some companies will classify jewellery as hypoallergenic if it has low nickel content, yet it may still contain enough nickel to cause direct contact dermatitis, so always be cautious and check the nickel release test report to be sure.
