Cup chain consists of a series of metal open topped boxes or cubes into which are dropped shaped glass crystals providing a repeating pattern of sparkle. The boxes are typically linked with a flat bar which allows the chain to articulate horizontally, with a little movement vertically. The stones come in a wealth of colours and finishes including crystal, crystal with aurora borealis finish, black diamond, as well as solid colours. This jewellery chain is very versatile and can be used as a standalone chain or worked into jewellery designs using cord, fabric, leather or wire.
