A necklace chain entangling preventer apparatus for preventing necklace chains of a plurality of 1<N≤3 necklaces from entangling when simultaneously worn by a user thereof, said apparatus comprising a first entangling preventer half and a second entangling preventer half, each said entangling preventer half comprising:
- a substantially flat rigid body plate;
- a plate-half attachment facilitator permanently affixed to said body plate for attaching said first entangling preventer half with said second entangling preventer half;
- a plurality of N substantially rigid necklace chain threading hooks permanently affixed to said body plate with a necklace chain threading separation between ends of said necklace chain threading hooks and said body plate, each said hook and separation configured for enabling the necklace chain of one of the N necklaces to be threaded into an interior region substantially circumscribed by said hook by passing the necklace chain through said separation and into said interior region without utilizing end-clasping hardware of the necklaces, and for enabling each of said entangling preventer halves to be freely slid over said chain thereafter;
- said plate-half attachment facilitators affixed to their respective rigid body plates with opposite mating configurations;
- except for said plate-half attachment facilitators being affixed to their respective rigid body plates with opposite mating configurations, said two entangling preventer halves being otherwise substantially identical;
- said necklace chain threading hooks positioned to vertically separate the N necklace chains from one another when the N necklaces have been threaded therethrough and the two entangling preventer halves have been attached to one another behind the user's neck using said attachment facilitators;
- and
- a plurality of N necklace chain threading retainers, selected from the necklace retainer group consisting of:
- a malleable material retainer, a pivot retainer, a pole retainer, and an opposite plate inverted hook passively-engaged retainer.
