Adjustable jewelry

An adjustable necklace, comprising:

• a snake chain, the chain having an outer diameter, a first threaded end, and a second threaded end;
• an adjuster slidably coupled to the chain, the adjuster being slidable along a length of the chain, where
• the adjuster includes a first orifice and a second orifice, each orifice having diametrical dimensions for receiving the first threaded end and the second threaded end of the chain, respectively, and where
• the chain forms a loop that may be placed around a wearer's neck when the first threaded end and the second threaded end are received by the first orifice and a second orifice of the adjuster, and where
• dimensions of the loop may be changed by slidably adjusting the adjuster along the length of the chain;
• an end cap threadedly coupled to the first threaded end and the second threaded end of the chain, the end cap having outer dimensions greater than the diametrical dimensions of the first orifice and the second orifice to prevent the first threaded end and a second threaded end from disengaging the adjuster;
• and
• one or more ornamental elements slidably coupled to the chain, the one or more ornamental elements being slidable along the length of the chain.
