Jewellery Materials & Care

Zinc alloy jewellery makes bold style affordable, but its reactivity and nickel content can lead to tarnish and skin irritation. This scholarly guide explains the science behind zinc alloy, how plating and nickel exposure work, and why hypoallergenic metals like 925 sterling silver, stainless steel, and 14K/18K gold are safer long‑term choices. Explore how JewelHub’s TR system and DuoTone™ stainless steel collections offer transparent, skin‑friendly alternatives.

Zinc alloy is a versatile metal blend used widely in modern jewellery for its light weight, affordability, and ability to capture intricate sculptural detail. While industrial zinc alloys vary in composition, jewellery‑grade blends differ significantly.
