A clasp with a mechanism to lock one or more keys is provided. The key can be affixed to an end of an ornamental item such as a chain, pendant, or charm. The clasp can include an inlet port for inserting a key and one or more channels for guiding the key towards one or more locking pockets. A compressible material can resist movement of the key along the channel and can prevent unwanted removal of the key at the locking pocket.

A necklace keeper or clasp for securing a jewelry item and for receiving one or more charms. The clasp includes a support member constructed of a support ring that extends less than a full circle so as to define a support ring gap, and a top head piece that extends upwardly from the support ring. A sliding lock pad engages with the top head piece and is normally biased to an extended position. A guide ring is providing having a channel for receiving a support ring and extending less than a full circle so as define a guide ring gap. The sliding lock pad has a lock position in which it engages the support ring to inhibit relative rotation between the support ring and the guide ring; and has a release position in which there is relative rotation between the support ring and the guide ring so that the respective supporting ring gap and guide ring gap each align.

A compressible material can resist movement of the key along the channel and can prevent unwanted removal of the key at the locking pocket.

A necklace or a bracelet includes a first clasp, a second clasp coupled to the first clasp, a first chain having a first end and a second end, the first end coupled to the first clasp, the second end coupled to the second clasp, a second chain having a third end and a fourth end, the third end coupled to the first clasp, the fourth end coupled to the second clasp, and a third chain having a fifth end and a sixth end, the fifth end coupled to the first clasp, the sixth end coupled to the second clasp.

A necklace layering and detangling apparatus with an integrated clasp that allows the wearing of multiple necklaces without overlapping, tangling, or otherwise moving relative to one another, and methods using the same, are presented. The necklace layering and detangling apparatus includes a first necklace attachment member having two or more necklace clasps, each clasp configured to be attached to a first end of a necklace chain or cord, and a second necklace attachment member having two or more loops, each loop configured to be attached to the opposite end of each necklace chain or cord. The necklace attachment members are separably attached using an integrated magnetic clasp. Thus, the wearer may put multiple necklaces on simultaneously by attaching the first necklace attachment member to the second necklace attachment member behind the wearer's neck using the integrated magnetic clasp.
