Why Anti-Tarnish Alloys are Hypoallergenic and Safe
Allergy sufferers rejoice. Discover the science behind hypoallergenic jewellery metals and how anti-tarnish alloy coatings protect you.
What Causes Jewellery Allergies?
Most skin allergies are triggered by nickel, a cheap metal commonly used to harden copper and silver alloys. When nickel dissolves in contact with sweat, it forms nickel salts that penetrate the skin, causing contact dermatitis—itching, redness, and blisters.
How Anti-Tarnish Barrier Coatings Protect You
Premium anti-tarnish jewellery uses advanced coating techniques (like electrophoretic lacquer or rhodium plating) that form a physical barrier over the metal. This barrier prevents sweat from reacting with the alloy base, keeping the metals locked away and protecting your skin from irritation.
Choosing Safe metals
Always look for jewellery labeled as lead-free, cadmium-free, and nickel-free. Choosing brass, sterling silver, or surgical steel bases finished with premium anti-tarnish coatings is the safest option for healthy, irritation-free styling.
