Abstract: The present invention particularly relates to a novel type of hinge to be used for sequentially interconnecting different elemental jewelry units of a jewelry item. Type of hinge constructions used in jewelry making of prior art do not permit the jewelry item to retain during use its appropriate shape which is required for bringing out beauty value of the jewelry item like the diamond-studded necklace. The necklace may present itself as an ordinary metal chain, which, as if, “falls down loose”, giving a U-shape or any other unplanned shape. Hinge-construction of prior art does not restrict movement of different elemental jewelry units in different unplanned directions. The difficulty becomes more pronounced when very small size diamonds are used in the necklace. The novel type of hinge of the present invention provides two mating pairs for each elemental jewelry units permit each unit to have predetermined appropriate amounts of clockwise and anticlockwise rotational motions.
