I connect the components of my kinetic necklaces so all the parts move. They are sterling silver and 18k gold-plated silver (vermeil); "Raku" copper; or Niobium. They include a 20" sterling silver or goldfilled snake chain.
For other necklaces this size, search for "Large Batik Triangle Necklaces." For other sizes, search for "Small Triangle Necklaces" or "Medium Triangle Necklaces."
