Methods and apparatus for precisely adjusting an article of jewelry to quickly and conveniently accommodate the particular fashions desires, size and clothing of the wearer. According to the invention, a flexible member, such as a necklace chain, is looped upon itself to form a loop portion, a first leg and a second leg. A slidable clamping device is mounted on the first and second legs of the flexible member. The slidable clamping device is adapted, in response to the application of an external compressive force, to slide freely along the lengths of the first and second legs of the flexible member, thereby precisely adjusting the size of the loop portion. When the external compressive force is released, the slidable clamping device securely prevents relative movement between the slidable clamping device, the first leg and the second leg of the flexible member. |
