An adjustable small parts holder especially useful in the manufacture or repair of jewelry is described. The device includes a body having at its upper portion two or more moveable jaws. The jaws have inwardly projecting upper end portions and are convergeable toward a common center external to the body. A linear supporting member such as a cylindrical rod is disposed along the longitudinal axis of the body, the upper end portion of this member being moveable upwardly toward the common center. A mechanism such as a rotatable collar is provided for moving the moveable jaws inwardly to cause their inwardly projecting upper end portions to converge toward the common center. In addition, a mechanism such as an adjusting screw is provided so that the upper end portion of the supporting member can be moved toward or away from the common center. It is particularly preferred to provide a cylindrical recess in the upper end portion of the supporting member to accommodate the post of pierced ear type earrings and other parts having a post or like protrusion. Additionally, the inclusion of this recess in the device enables the user to employ of any of a variety of differently shaped auxiliary holding members mounted on posts. In one particularly preferred form, an auxiliary holding member has a bowl-shaped upper surface with a slot extending through the outer wall of the bowl. This form of holder is particularly well suited for securing small pendants, screw-on type earrings, and other objects having an extended portion that may be accommodated by the slot.
