The hooks are silver-plated and nickel-free.
It is possible to replace the hooks for Niobium. (Extra charge 4,50 €).
Niobium is a chemical element (symbol Nb). It is a soft, grey metal that is naturally found in the minerals pyrochlore and columbite.
Niobium is naturally hypoallergenic and commonly used in a number of medical devices including prosthetics and implants, such as pacemakers.
Often used in jewelry making because of its hypoallergenic properties, this metal is a safe choice for anyone with metal allergies . Niobium is highly malleable, lightweight, highly resistant to corrosion, and hard. Additionally, when it is heated and anodized, it can result in a vast array of iridescent colors.
Niobium jewelry findings are good alternatives to precious metals.
Findings made with niobium are hypoallergenic because they do not contain any nickel alloys, so they are safe for someone who is allergic to jewelry with nickel, copper, or other base metals  and alloys.
Niobium is relatively easy to work with and can be easily cut with a jeweler's saw or forged with ease. It cannot be soldered using standard soldering equipment. Niobium alloys, or mixtures, are used for a number of pre-made jewelry, including earrings, rings, and other piercing devices. The hypoallergenic property makes niobium jewelry a safe and popular choice.
