The jewelry system of the present invention is used for easily layering jewelry by connecting strands of similar types of jewelry, such as necklace strands, into a layered jewelry piece (multi-strand necklace), and which prevents tangling and provides a distinctive presentation of each layer. The present invention allows for variety in the combining and re-arranging of individual strands in any desired order, by the use of end couplers on the ends of each strand and one or more connector pairs disposed on one or more of strands. This allows for the creation of customized layered jewelry pieces that can be adjusted to suit a variety of styles. The design of the present invention allows for the use of singular strands to form into a layered jewelry piece that is distinctively presented in a symmetrical, cascading arrangement, which moves uniformly as one piece with the weight of gravity, virtually eliminating the risk of tangling. An additional purpose of this system is to have more versatility for the user's jewelry and increase the convenience of wearing fully constructed, customizable, layered jewelry pieces which can be put on and removed as one piece.
