Fish Hook Clasps are a type of necklace clasp that has a hook like element that fits into the main body of the clasp to secure it.
24. Foldover Clasps
Foldover Clasps are a strong, functional snap shut fastener, similar in design to those used on metal watch bracelets. They have a hinged front face which can be raised to allow a loop or ring to be placed within the body of the clasp before being closed down on to a pressure tab that keeps the claspsecurely closed. By design they take a degree of effort to open them and are therefore far better suited to bracelets than necklaces.
25. Guard Chains
Guard Chains are small chains, several centimetres in length, that are attached at one end of a necklace or bracelet close to the clasp, and at the other end to a loop or chain link on the oppossite end of the piece. It is used as a fail safe device in case the clasp fails open unexpectedly, ensuring that the item of jewellery does not fall away from the wearer unnoticed.
26.Hidden Screw Clasps
Also known as Ivory Clasps
Hidden Screw Clasps are a necklace fastening that consists of two short barrels with screws that connect together to form a secure closure. Each part of the clasp is partially embedded in to a bead or pearl so that when the two parts of the closure are screwed together the clasp closes to form a rounded bead.
27. Hook And Eye Clasps
Simple by design, these Hook And Eye Clasps are, as their name suggests, made up of two elements, namely a hook and an eye. The hook element is attached to one end of the jewellery piece with the eye at the other end and the clasp is secured by catching the hook within the eye. These closures can be simple wire forms or more decorative and with a suitably gauged jewellery wire they are very easy to fashion. They are perfect with heavier designs as the added weight ensures that gravity keeps the clasp closed.

Ivory Clasps are a necklace fastening that consists of two short barrels with screws that connect together to form a secure closure. Each part of the clasp is partially embedded in to a bead or pearl so that when the two parts of the closure are screwed together the clasp closes to form a rounded bead.
29.La Loop Findings
La Loop Findings are an open ring or split ring that has two swival findings attached. When a neck chain or cord is attached to the swivals it allows a pair of eyeglasses to be attached and has the effect of reducing twists and tangles.
30. Lanyard Clasps & J Hooks
Lanyard Clasps or lanyard clips operate in the same way as a lobster clasp but without the aid of a mechanism. Instead this closure is opened by applying inward pressure with the thumb against an overlap of wire where the fastener opens. The tempered metal ensures that once released the clasp opening will spring back to the closed position, with the overlap ensuring everything remains secure. Typically used as zip pulls and for identity tag holders they have also found a place in jewellery design for decorative pieces such as handbag charms.
