Necklace with Adjusting Length Beads

A slide bead, for a chain of a specified outer size, comprising:

• an outer surface, formed of a first material;
• the outer surface having a first opening at the first end and a second opening at a second end, and an internal cavity extending between the first end and the second end;
• the outer surface having a structure to which the chain can be attached;
• an inner surface, formed of an insert made of a second material, the insert formed of a diameter effective to allow the chain of the specified outer size to be moved by force, but to prevent the bead from moving relative to the chain just from the weight of the bead.

A method of adjusting the length of a necklace, comprising:

• providing first and second slide beads, where each of the first and second slide beads is connected to a piece of chain, and also has the opposite piece of chain passing through a central location of the slide bead, where the central location of the slide bead is formed of a material effective to allow the chain to be moved by force through the slide bead but to prevent the chain from moving through the slide bead without applying force;
• shortening the length of the chain by pulling the beads along the chain, and moving the first and second slide beads away from one another, to form more doubled up chain in between the first and second slide bead;
• and
• lengthening the chain by pulling the chain through the beads and moving the first and second slide beads closer to one another, to form less doubled up chain in between the first and second slide beads.
