King chain (jewellery chain)
A king chain is a named style of jewellery chain used for necklaces and bracelets. It is available in different dimensions and materials. A Norwegian silversmith describes the pattern as nearly square in cross-section; the thickness of wire used in handmade examples is not the same as the width of the finished chain.
The name alone does not establish material, fineness, age, or whether a chain is handmade. These details should be assessed from marks, construction, documentation, and examination of the individual piece. See also breikjede (panserkjede) and slangekjede for other chain styles.
